If You Fly a Drone in a Car, Does it Move With It? (Dangerous In-Car Flight Challenge)
HTML-код
- Опубликовано: 11 окт 2024
- In this video I test what happens when you fly a drone in a vehicle. Will the drone stay with the car as it moves or will it stay in the same location relative to the ground? First, I test what happens when all the doors are closed and I try to fly the drone in the car, then I test what happens when I leave the doors and the trunk open. This is a really neat idea that teaches about frames of reference and also air resistance, and a little bit about how the Mavic Pro works.

Hey everyone, I'm already seeing comments about this, don't forget that this does not mean that if you are moving at constant velocity in a moving car and jump that you will fly to the back! That is because when you are moving at a constant velocity you are going the same speed as the car already so there is nothing that would push you to the back of the car.
What if the cars stopped you jump and they floor it?
Cool video! This is one of the best proofs the Earth is flat! :)
The Action Lab it would depend whether the car is accelerating/decelerating. If it is a car going at a constant velocity, then you wouldn’t move when you jumped.
The Action Lab actually if you jump and while you are in the air they either speed up quickly or break quickly you will not stay in motion with the car
The Action Lab hey can you try to put polyethelyne glycol in a blender ands see if anything changes?
You need to put the Drone in atti or manual mode, it's trying to keep its self in the same place with whatever is beneath it via the optical sensor.
It was in atti mode
Plus the transparent protective cover of the drone is not removed ... you can see the gimbal attempting to move.
The Action Lab hmm, well I know the down facing sensor is always active but I think you can put the mavic in manual, I have one I'll have to check, I just haven't flown in a few months because it's been freezing in Chicago.
The Action Lab I think it also uses GPS full time, but again I can't remember, but be careful with those plastic blades, early on I helped organize the Drone Racing League, I built a lot of racing drones, and one time the Drone went nuts and I literally had 20 deep Cuts in my thumb, I think I have it on video but I was spurting blood all over the place. I called those blades the plastic Chinese Ginsu knives. Those suckers are sharp no joke, I use all carbon fiber now.
Warped Perception bro, its physics. He tried to do it as analog as possible.
You need a racing drone for this test, the Maverick is too advanced, the GPS compass input is not matching the down facing Optical sensor. It's trying to keep centered on the landing pad, but the optical stabilization input isn't matching the GPS or Compass input. It's essentially just confusing the flight controller because it's all mathematical.
What he said🖒
Didn’t he say he turned all that stuff off?
Cappuccino - I’d imagine the drone had some stability assist systems such as trying to keep itself level with the ground etc. Those probably dont have an option to be turned off since it would be near impossible to fly a drone.
Tayfun Akin the
I didn't understand what you just said, but it sounded very smart
WTF THE CAR STARTING LEVITATING AT 4:24
Tangy Toast lol
Tangy Toast ,Lol it does look like is levitating when you look at the windows jajajaja , that's funny.
Well, the drone was reving pretty hard.
TJ Carlin Vlogs. It is on the video. It levitated. Watch it again.
Kick Saunders. Good ad cor that drone. Look! My payload is a mini van. Beat that Amazon.
I always had such a question in my mind about fly in a bus , thanks for this👌
Hhahaah yeh
Thought it was only me
lol reading the comments on this guy's videos makes me feel like I'm somehow not as stupid as I thought I was
Mike Wazowski that is exactly what i was thinking😂😂😂😂
Mike Wazowski Haha
😂
Glad I’m not the only one that uses their significant other as an assistant
The Nocturnal Alchemist They signed up for it when saying I do..
The Nocturnal Alchemist ofcourse IT Will not Stay in the car if you move it
I'm glad I'm not his significant other as his assistant.
Hey lad I love your channel. Keep up the good work mate!
The Nocturnal Alchemist I saw u in the ductape glove video
When I was a kid, I've seen a fly buzzing around my face inside the car, while we were at high speed. I've thought, "How could a fly keep up with the car's speed?"
But to the fly everything around it was stationery same that it is for you. If not for the windows and g forces you'd assume you were stopped.
@@shawnwise2458 I'm stationery relative to the car because I am physically connected with the car. But the fly was suspended mid-air and was not touching the vehicle, so technically, it should not be stationery relative to the moving car.
@@cindymananzalamartinez6679 but because the car was basically a chamber it blocked all air flow so no drag other than gravity. So essentially it was as if the car wasn't moving.
@@shawnwise2458 You're right. The deciding factor here is whether the windows are closed or not.
@@shawnwise2458 i have always wondered the same thing. Can i please get scientific explanation ?
Friend: hahahahha look at that phone man
Me: bitch this is a fidget spinner
I AM DERP. no shit! So what
The car is changing speed from 0 to some speed positive, so there's acceleration. When there's acceleration, the drone won't accelerate with the car. But if the car is moving at a constant speed, without acceleration or deacceleration, maybe it will stay. Need to redo this experiment.
Gerard Tan yeah, relativity
Gerard Tan it was given to him
it will not lol unless it is attached to car. Any movement will not affect the drone as it is not attached to car in any way.
Gerard Tan I agree. The whole opening the windows and doors was pointless.
You have to factor in that the mavic has a optical down facing sensor, it's going to try to stay sooner with whatever is beneath it. But in this case the flight controller is just getting confused.
Hahaha jesus everybody who visited highschoool knows whats going to happen
Hoichael Stoderzinken his audience contains children who don't know. Don't be so self centered
so whats going to happen? i dont know, though ive been to highschool
Or read the comments
Jesus said worry more about spelling high school correctly.
Daniel Guzman yes
what about flying a drone in a plane while it takes off? LMFAO
I thought you will initially run the car at constant speed and then fly the drone. Path of car should be straight.
No that wouldn't work because the drone would then have an initial speed and direction. It wouldn't be lifting off from a standstill position.
Aaron Lowe but it would be a nice additional experiment. I would rather have seen that one, but I’m sure there are lots of difficulties
@@jestes7 I suspect it would move as people do when they're not secured to something. For example, go round a corner and they lean the other way. Jam on the breaks and they fly through the windscreen.
Aaron Lowe but each scenario you are describing requires a change in momentum so obviously that would happen. What I’m wondering is what happens when just going at a constant speed.
Trung Lam that’s a good prediction! I would guess that too. But unless you’ve done the experiment who knows for sure! In a vacuum (space) you can maintain momentum, but in a car it is not a vacuum, but I’m thinking that the additional factor of air transfer from the drone (as shown while driving slowly in this experiment) would help keep it positioned and moving with the vehicle.
Maybe a small chance, but I could also see the drone ever so gradually losing momentum and not being able to maintain the same speed as the car, and eventually hitting the back of it.
So had this test been conducted in a way that made actual sense, he would have started moving the car while the drone was on the floor. From there he should bring the car up to a constant velocity. At this point, he can begin to hover the drone, which would show that the drone will only move upwards and NOT backwards due to Newton's first law. This can be related to how you can stand up and walk around on an airplane without falling backwards once it is moving at a constant velocity.
At this point he has the drone hovering in place while the car is moving at a constant velocity. Next, he would have the driver slowly accelerate the car (press slightly harder on the gas pedal), which would show the drone begin to move backwards, since the drone itself does not experience the acceleration that the car is experiencing due to the fact that they are not touching. That can be related to how you feel yourself be pushed to the back of your seat when a car accelerates, but since you are in contact with the car, you don't fly out of the back.
Santy G thank you
Santy G
Exactly. Thats a fairly dangerous test, spinning props and all. But anyways
Until it has friction with the car, or something else that does, it has no outside force on it, except the cars atmospheric gas. Which is minimal.
But. If it was a mini-blimp, results would differ. If a car accelerates with a helium balloon in it, not only does the balloon move with the car it accelerates faster than the car. Since the atmospheric gases (air) in the car have no friction, it stays put. It slightly compresses at the back of the car where its all accumulated. Since helium is lighter than that gas, it gets pushed to the front of the car. Atleast until inertia balances everything back out for a few moments. Right turn, balloon goes to right side of car. Hit the brakes, goes to the back of the car, etc.
Nerd
Santy G
Sault _YT except that he is wrong.
I've always thought about this when I was a kid and I saw a fly or something in the car.
It's funny to see that someone actually made a video on this ^_^
E drop another ytber did it and it was better
Oh my god same !!
Same
E drop it he air is not moving the car is the air is moving with the car
SAME
Looks like someone skipped physics class.
lol
Since you didnt, please explain
How'd you know dad?
Ok kindly explain... Im waiting
Its because of the air
DJI Mavics have two sensors placed on the bottom of the drone to keep the drone in place while in take off. That's why it stayed where it was. 👍🏻
Biggsy Those sensors are only for altitude.
And it is a collusion sensor that’s why the drone goes up when he put a plastic cover beneath it
Markus The Mechanic There are no collision sensors on the bottom
That is a proximity censor / ultrasonic censor
Markus The Mechanic It is called sonar and it it only used for altitude stabilization.
No safety glasses or nothing. Lol be safe man🤓
Your laughing at a man that could possibly injure himself? It’s his life so he does whatever he wants I remember when I was six I jumped off a bike going 80kph down a hill without any safety and I lived!
Piemack2006 next time wear a helmet🤕
crazy russian hacker?
@El Capitano Kapitan it's is the 1 priority in your country he's in Get you facts straight before you comment
This happened exactly the way I expected. These types of drones including the new Phantom and Mavic Air drones use a mix of ground position detecting sonar as well as GPS. If the GPS was turned off this experiment may have lead the drone to stay exactly in place with the car. For the first few feet the drone would be confused with the confliction between the GPS signal going through the car and the sonar sensor. It would just think that while the car is moving it would consider itself being offset from either being pushed by something like another person, object or the wind and realign itself, but when it gets too far it will priorities the GPS as they are both generally mixed to keep it steady as far as I know. This being said, turning the GPS off would give better results, but if it does happen to see outside of the car particularly with newer drones that have front, rear and bottom sensors it may still see that the car is separate from the ground outside. However if it just can see directly down with the GPS off it 'may' be more likely to stay in place as long as the car doesn't move too fast, the equivalent of the force of wind pushing it at it's max realignment speed.
I literally have been thinking about this for the past 2 years at least, but never actually searched for it, but mine was in a moving plane, but this will do. I’m glad someone made this experiment. 😂
This isn't a real experiment. Although anyone who has taken high school level science already knows the answer, the only way to really demonstrate it is to have a drone without GPS, and one that is much smaller (or a vehicle that's larger). In such a closed space, your aircraft will never be out of ground effect, and the turbulence created by the rotor is going to push it all over the place (which is one thing you are experiencing). Get something small like Ares helicopters- they are pretty rock solid just based on the internal gyros.
Many people will though, since he concludes something from these trials. So to me it is important to point out the flaws in what he does, since that is part of science, right? Testing the hypothesis and everything around it beyond the shadow of a doubt. :)
Lone Madrone I agree your exactly correct
well are they testing for speed or acceleration?
One of these will work; other will not.
Go on highway or empty road; maintain constant speed and direction and it will work. Something something; bodies in motion...
devops'y a body in motion tends to stay in motion, while a body at rest tends to stay at rest. Yet the experiment starts at rest(theoretically)
yep; what i was alluding to.

If you can throw a baseball at 90 mph in the opposite direction of a vehicle you're in going 90 mph , will the baseball just hover in the air in one spot ?
Ja Z Yes. The mythbusters filmed a simliar experiment with a basketball I think.
From the perspective of a person outside the vehicle it will appear as if the baseball just fell straight down as if dropped. All movement is relative, that is to say you cannot define absolute movement, you can only say "this ball is moving relative to me".
Ja Z nice
It will hover/fall in one spot - the spot you were in when you threw it. Which would become 'out of the back windscreen' very quickly if you were going 90 mph.
What if there's 100mph wind and you are driving 100mph in the same direction
Me trying to do an experiment bout this: jumps in car to see if it works
My parents: what the hell are you doin
Terrible execution
Kyle Sheffield u mom da big geay
Here is the hypothesis for you. I should rather call it a fact. But I m gona call it a hypothesis. Provided that you make measurements as accurately as possible,
No matter how fast the van is moving, 60 mph, 100 mph, or any arbitrary speed. Provided that
1. The windows and all openings of the van are completly closed such that the outside air cannot interfere with this experiment
2. Provided that the van is already moving at a constant speed. I.e. its velocity is not changing at all. (Before the experiment begins and untill the experiment ends.)
3. Provided that the van is moving along a straight line only.
The drone will hover in one spot as if it wasnt moving at all. As if it was on the ground and hovering over it.
Please try the experiment. It will be fun. Be carefull though dont cut yourself. I would suggest tying the drone with strings and fixing it to the van such that its movement is limited but is not constrained in the 3 spacial dimentions provided it is within a required region of space as permitted by the strings. I would love to see this done. Thank You for reading.
rituraj phukan What you have left out is whether the van starts moving or is already in motion. That's the most important.
He confused acceleration at speed. It's acceleration that makes it displace. The velocity doesn't matter if it's constant
Dizastermaster, I have said velocity must be constant. If he is accelerating how can velocity be constant? I mean if he confuses between the two terms,yeah that is a possibility...
Dizastermaster I have edited the comment. Thank You
"If he is accelerating how can velocity be constant?"
It's not. But when he was referring to going "too fast", he was actually meaning accelerating too fast. The speed you drive doesn't matter. Just the acceleration.
Haha.. 1st try to keep it steady
What i love about being human is our collective thought process. I just thought about this a few minutes ago and knew someone, somewhere has thought of the exact same thing. And luckily i was born in a time when im able to access other people's minds as well as their experiments through the internet.
hey, you are not alone, i 've been thinking of it for many many years :)
The drone will keep moving with car in one case only, if you take off while the car is already moving forward because then the drone has it’s own energy of moving froward before it takes off and after a while of flying the drone will start to lose the energy of moving forward and will be separated from the car.
I haven’t tried this, this is only my opinion from my knowledge :)
Alaa Alahmad yes, like us on the spinning earth
Almost. It actually depends if the car is traveling at a constant velocity or accelerating. If the vehicle is moving at a constant velocity the drone will just sit there (assuming a perfect hover) but if the vehicle were to accelerate it would move back relative to someone sat in the car.
The drone is experiencing no air resistance within the vehicle assuming door and windows are closed, its not a perfect system but its close enough. You could do the same experiment with a tray and a small ball, place the ball on the tray and accelerate or decelerate and the ball moves... place the ball on the tray while the vehicle is moving at a constant velocity and it will stay in the same place.
if the vehicle is enclosed and moving at a constant speed the drone will just move along with it until the vehicle decelerates or accelerates the "foward energy" doesnt get used up because from the drone's frame of reference its not moving
This is all assuming that the GPS is disabled.
Alaa Alahmad The drone has downward sensors and will move with the car if not connected by gps
He needs a rc helicopter,
Not a drone with GPS and motion sensors
dakota graham He's struggling flying a Drone, Rc Helicopters are very complex to fly, not everyone flies them (I mean real RC helicopters, not that cheap shits found on any toy store)
Diego Andrés Luna Hernández
A cheap one
Not a big expensive one
Diego Andrés Luna Hernández just something that hovers in the air
With no sensors of any kind
dakota graham Gps and motion sensors on a drone can easily be turned off. So no rc-helicopter needed for this experiment. I fly both.
I agree. I get the point of what you're saying. He needs a simple $30 Amazon special. Better for the experiment and WAY cheaper if damaged
Walk inside a flying airplane ✈️ in the direction of the plane.. now you are moving faster than the plane (plane initial speed + your speed)
MDS Minecraft 45 Repeat the experiment with a plain that's going almost at the speed of light. EXPERIMENT FAILED
Ricky Pazzi plane*
Ricky Pazzi No Mass Can Travel in the speed of light... experiment impossible👍
MDS Minecraft 45 You don't know that for sure though.
William Mosley No.. Its true!
You need to do this inside of a big truck/moving van so there's room for it to really move around. The car is too small, these things tend to wobble a bit anyway so it's hard to tell what effect the car moving is having on it.
Video starts at 1:32
Okto - osu! and Stuff thank you sir
Wife should have reversed it instead really fast and shout afterwards
"IT WAS JUST A PRANK BRUHHHHH"
I've done this before with a smaller drone. It isn't affected by the movement of the car.
Also, I launched the drone once we had finished accelerating on the highway (about 50mph). If we suddenly slowed down it would fly into the windshield, and it we suddenly sped up it would fly into my face.
+TurkeyBoy55 that’s cool. I think that the smaller the drone compared to the vehicle the less effect the vehicle has on it too.
The Action Lab it's not size, the Mavic uses GPS to stay at his original location. That's why it moves back when you drive the car.
You should drones with guarded blades when you do these experiments! In my opinion, ALL drones should have guarded blades. Eyes are too precious to lose.
a better idea would be not to fly a drone into your eye
Yes, but with that philosophy, you would not wear safety glasses when doing work where high-speed projectiles could be generated. You are working in close quarters with the drone, in a dynamic situation, precisely when such encounters are inevitable. Furthermore, propellers wont get broken or motors damaged. When a drone encounters a vertical surface, the doughnut-shaped airflow around it is disrupted in a manner that "sucks" the drone against the surface.
Or fly one of the small toy ones instead of a big one
Small ones can injure eye easier then the large ones! They are typically flown indoors or in close proximity to people.
No it won't. First, the guard can be thin so it doesn't disrupt airflow. Second, the guard can be part of a duct to actually improve the performance of the fan. It biggest disadvantage is the additional weight.
The gps is what is creating the bizarre behaviour you are witnessing!
Think Lab He said he turned it off.
Papii Chuloo actualy manual mode doesnt mean its not going to stabilise with gps.
it think you mean atti mode witch is only activated when gps and the vision systems are unavailable.
the only thing sportmode does is raise the speed and the gains on the remote and disable forward obstacle avoidance .
trust me i flew (and crashed) drones without stabilisation.
I would say its they gyro and accelerometer
gtjack9 you claim to have a mavic pro and yet you fail to realize the mavic pro does not have a toggle for Atti mode (manual) and on mavic pro Atti mode is a hardware fail safe for when other systems are offline like the GPS is unable to lock or IMUs are down...
However this being said the reason the mavic pro or any modern DJI drone would be able to keep up in the car and hold position is because of the VPS and IMUs... VPS is a visual positioning system, uses the dual down facing cameras and dual front facing obstical avoidance cameras to estimate changes and adjustments.. the IMUs are inertial Measurement Units and they are measuring external changes that are impacting the drone like for example the turbulence pushing the drone up or down or away.. VPS sees the ground has moved along an axis and it attempts to compensate while the IMUs are saying that minimal change has occurred for what the VPS change was and that’s why the drone was unsteady and moving to the side a lot..
literally if you want to do this properly, you need to have the car moving initially, then fly the drone so it gets the movement of innertia from the already moven car, but the trick is to have a constant velocity that doesn't change, acceleration would ruin the experiment, you want a steady speed, and I bet you the drone will stay in one spot.
Xanh if car was moving at constant speed the whole experiment wouldn't make sense.
You should try it in a larger vehicle like a bus or something, you may get better results imo.... very interesting indeed I always wondered this since I was a kid when I saw a fly in our car thinking if he has to work harder to fly when the vehicle was in motion? Either way good good job Joe
F
acceleration vs speed; two different things. If a vehicle maintains same rate of speed and direction; then it will fly exactly the same as on earth; which is also moving at 1000mph or so.
Newton's First Law...
its a generalization; if we want to be pedantic its 1000mph when referenced from the planet's center compared to the equator.
In theory we are 490,000 miles per hour when compared to the great attractor; same idea...
Thinks it’s a cool experiment, wife thinks something else entirely. She starts studying divorce law.
You had to use a 1000$ drone
ReKt SoN he should've used those pocket $9 micro drone
Yes because the mavic is very stable. Better for the circumstances of the experiment
Ratchet Bunny "very stable"? He could barely hover the thing
Maybe he just doesn't know how to trim it out. So he was constantly micro adjusting it. Could just be because the van is such a small space so its causing turbulent air, because I've seen Mavics be more stable outside with a breeze.
Problem is it also uses camera to keep its position so this experiment is flawed. The flight controller will try to keep the drone inside the car, but the forward accelerating car would otherwise not get the drone to follow.
Genuinly always wanted to know that
Could've just tried google ya know
Bomara do u relaly think it woukd be on google + google know always right ya know
Or you could've just thought about it for about 2 seconds.
I love your channel
I've been wondering about this for 2 years thank you.
I found a couple of issues watching this. With the video, it wasn't clear what was going on. The accelerations and decellerations were subtle and the video (and narration) didn't suggest clearly when exactly we were accelerating, when we'd stopped accelerating, how fast we were moving, or which way the thing 'wanted' to go.
Secondly, throughout it wasn't clear whether the adjustments were yourself trying to stabilise it, or due to the car's acceleration or something else. Much like trying to test divining rods, we had the experimenter influencing the results. Thanks for going through the trouble, but this wasn't a good test.
Jay Smith I'm very surprised he didn't mention the fact that any movement made by the drone itself in any direction will cause it to accelerate. Only if the drone stayed 100% level will it have 0 acceleration besides up or down. Also the drone itself has lots of onboard features that kept it in place during the tests. (notice how it fixed itself after a second or two of moving backwards) It is very obvious that say a cheap RC Helicopter with just the blades and the hover function that locks the controls once it's level, will hit the back of the car after it starts moving.
The GPS in the drone was doing that.
I agree with Jay Smith. Couldn't have typed it better
I think every kid has kinda tried this with a balloon
The ballon will move to the front actually for different reason....check net
Sudarshan Pujari I've done it many times when I was young. Balloon never moved
+J⃟O⃟N⃟A⃟T⃟H⃟A⃟N⃟ S⃟C⃟H⃟U⃟L⃟T⃟Z⃟
then you did it wrong. That would be like saying your head wouldn't move when the car accelerates. hint, it does.
james pogrebetsky how does one hold a balloon string to it floats in the air wrong?
The reason your head goes back is because of some gforce sciency stuff being connected to the car
Air does not move backwards when you go fowards unless a windows open.
I've done it a ton of times when I was little and I don't know how you'd do that wrong holding the string or not they didn't go back
J⃟O⃟N⃟A⃟T⃟H⃟A⃟N⃟ S⃟C⃟H⃟U⃟L⃟T⃟Z⃟ you might want to try it again, as an adult. It’s basic physics.
OMG! You literally just made me understand the concept of quasi equilibrium process in my ThermoDynamics engineering class. I couldn’t rap my head around the concept but after this video, it really did. Thank you sir
Please explain me too
If you were floating inside of a train car and it took off, would the walls slam into you? Yes. 😂
This all has to do with compression of the air within the car. Its the pressure variants causing the erratic motions of the drone and the air is slightly compressed when the vehicle changes direction. I'll paste my previous reply here:
A balloon filled with air will do the same thing. When you take off it goes rearward because the gas in the vehicle attempts to stay at rest and create a high pressure zone in the rear and low Pressure in the ft (when driving forward). After the initial static friction is overcome, it will go back to where it was.
To prove this inflate a balloon with helium and go forward... what just happened? The balloon went forward because the buoyancy of the lighter helium molecules are moving away from the now slightly compressed denser volume of air in the rear.
That's what he says in the video.
The RUclips channels, SmarterEveryDay and IST Science showed how a balloon moves inside an accelerating car. Sometimes, accelerating forward makes a floating balloon move forward relative to the cab of the car.
@@jerrybobteasdale the problem with a balloon is it's easily effected by other forces than the ones being tested.
fidget spinner phone?
cool, now all we need is to connect the spinner part to a dynamo so we can charge our phones by using them as fidget spinners

That's innovation bro
meepy MC ;
Should do this again with a mini drone. Much better and stable in small spaces.
preston121068 well, a mini drone would make no difference, just that it’s smaller so it can move more before hitting the side.
Preton121068 l agree with you

This is so funny because I thought I was the only one who wondered this😂
Pretty sure the drone won't move with the car, bcuz if u stand up or something in a car, when the car moves forward u start tilting backwards, like ur not rlly moving but ur touching the car and the car is pulling u. If the drone is in the air, the car can't pull the drone with it. But I always wondered this OK IMA WATCH THE VID NOW
tinypaws' gaming lul aerodynamics
The drone will move with the car if it is first placed on the car, and starts flying after the car is moving at a constant speed. Acceleration is the main thing here, aerodynamic's effect is minimal in my opinion :3 check out Newton's first law
Edit: when you tilt backwards as the car starts moving, it's because the car is accelerating, and you have the inertia to remain stationary ( just like the drone in the video which was not in contact with the car when the car starts moving XD) Gravity & friction then pull you along until you've reached the same speed as the car
An object will keep at their velocity if there are no net forces acting upon it
tinypaws' gaming how old are you bro
TechThisOut er 15
I hope Joanna got paid to help 'cause that was dangerous LMAO
all the highschool passed..
JUST LEAVE
My M8 no
My M8 but I'm curious
Edit: wrong person
redstone craft guy oops didn't mean to reply to yours, sorry
Obviously you didn't. Go back and learn some sentence structure
I think you should move the car first , then you should fly it and , with constant speed regardless of the speed quantity .
Awesome experiment! Normally, going in a straight-line direction at a constant velocity should allow the drone to travel with a moving object (a.k.a the van). Assuming the van has all windows closed and no outside air is affecting the inside air.
HOWEVER:
One major factor that you didn't seem to consider was that the DJI Mavic Pro uses GPS to maintain it's absolute geographic location - and that is why the drone appears not to stay with the van. That is to be expected since the drone is programmed to maintain it's location!! :D
I want to clarify some things, if there's a window on top car and you jump out of the window and into the air, would you be able to get back to the car on the window or it would mean you gonna get hit into the street because you move at a lower speed then the car?
4:00 lol I can see your brain working so hard right here
Try a drone with out gps or turn off the gps.
I think simple experiment can be done with a mini drone. Just set a certain speed of the propellers which makes it (drone) float in the air and then tie it with a thread to the ceiling and then drive the car and see which way it moves from the center marking point.
I think the GPS was off because the lights were flashing red and yellow. It should be green when it has signal.
Try actually watching the video. He literally says that he turned it all off.
mrodg88 lol I tried. I just couldn't. Not the whole video.
A "drone" without GPS is not a drone. But nice try
Hey dji drones have GPS stabilization so your test worn work right
Kyle Vardy and no info if downward vision was disabled. It would have helped it to stay in place. And there are propeller cages for the Mavic, would have been a smart move to use instead enclosing oneself in a big blender...
Same concept as a fly inside a flying commercial jetliner
Airmanmx1 True, but I can't remember ever seeing a fly inside a plane. It's odd.
DLJ pls don’t tell me you are one of those “matrix” is real. Oh I haven’t seen a fly inside an airplane so it must be a glitch.
Airmanmx1 - no, I'm just someone who makes silly jokes. Although I genuinely can't remember seeing a fly inside a plane.
DLJ ever jumped in an elevator right before you know it will stop?
Airmanmx1 What happens?
Another example to clear the doubt, this experiment is just like why a plane can't just move up in the sky and cover the distance as earth is moving even when plane didn't move forward or backwards. It stays at same location because Earth's environment works as a closed air container (just like this car, in this example, it would actually move with object if instead of car it's a closed train compartment). So this video of yours is a wonderful science experiment. Thanks got making it.
its all about the acceleration, if you accelerate or you hit the breaks (which is also an acceleration just in the other direction) the drone does not accelerate with the car (obviously) and the drone is NOT able to move with it. the speed of the car does not matter its all about the acceleration of the car. if you start flying the drone while the car is already moving fast and at a constant speed you can easily fly the drone but if you keep accelerating or hit the breaks (as earlier explained stopping the car is also an acceleration just in the opposite direction) then the drone will smash against the window (depending on how strong the acceleration is)
So where did the drone getting the speed?
@@giftthischristmas1502 i dont get what you mean
Acceleration or deceleration or even constant speed, the drone must get the push from somewhere.
@@giftthischristmas1502 you mean if the car is fast and you start the drone while the car is fast? then the drone got the speed from the car while it was not flying. as soon as the drone is flying it will no longer get and acceleration from the car? i am not sure if i understand your question
Pls try to fly it in a lift :3
missing.no_ Casey neistat flew one in an Emirates plane so...
Lyft
Biggest issue with lifts/elevators: they're rarely going at a constant speed; it's almost always accelerating or decelerating. This will make the flight crazy erratic. Now if the lift is moving at a constant speed, it gets boring.
Just a theory but with the windows closed it is kinda like its in a sealed atmosphere “no air movement “.
But at the same time the drone is gps locked so wouldn’t it be trying to stay in its gps locked position until you give it any control input? I’d be curious to see what would happen with a drone with no gps?
In the process of trying to stay safe you instead almost got your Face sliced open by the blades lol Nice thinking though
But I have observed that if a fly is flying in the car it moves along with the van.
TRY TAKEING OFF WHILE AT SPEED ON THE FREEWAY, WINDOWS CLOSED AND THEN OPEN.
That was an interesting experiment. I remember tethering a helium-filled balloon to my gear shifter, and it floated in the opposite direction than I expected as I drove. I guess due to the way that the air moved inside the car with the windows up. I wonder if the drone is influenced similarly?
🚐🚋🚌🚈
That is one question I always have in my mind. LMAO.
Try getting on the highway doing about 65 and then start flying and see if it can keep up.
Andrew Conner lol of course it will, it's starting at the same speed as the car
Andrew Conner
If and it is a big if you are able to very slowly accelerate up to 65 MPH then it will adjust to the speed of the car. If not then it will just hit the back.
Jamal Mahroof Of course its starting at the same speed. That's why I said see if it can keep up.
acdbrn2000 No, you pick up speed and then start flying, no need to adjust for anything.
Dizastermaster
Then it is already is aready at speed and it will be fine. You can travel at 65 MPH or any constant speed and throw an object "straight up" (from your relative perspective) and it will fall "straight down" back in to your hand since the ball is already traveling at speed. For the drone it is also "connected" to the vehicle by the force of the air it is pushing and that is pushing on it so unless annother force acts on it it should hover.
I’ve always wondered about the same thing 😂glad to know I’m not the only one
I dont know is it the same thing or not but can it explained why when helicopter fly in a vertical movement for some hours without any horizontal nor diagonal movement then landing verticaly with the same track as when the helicopter fly, is still landing in the same exact position just like before the helicopter flies even though the earth rotation velocity is 460 meters/s?
Yes, it's the same thing, that's why you could move/walk normally and doesn't feel anything wrong in the car even though the car is moving
You should try it the other way round, find a long straight road and move at a constant velocity, while the drone is started on the round, at constant velocity, then lift off.
My 1yr old daughter can walk faster than that car did.
Except that the purpose of the video wasn't going fast. Wanna try if a drone stays with your daughter too? ...
Luke Tipping no one cares dude
Horrorscope Gaming Evidently not.
Reechey. Grammar, people...
I didn't know cars could walk
Thanks a lot......this was the thing running around my head since my childhood....no one understood my question all these days..... thank you action lab 😍😍😍
I also have been thinking about this for years.
Why didn’t you try driving at 50 mph windows closed
2:15 bro almost died in the name of science
At 4:35 the van looks like its floating away
1:33 er... you may want to, you know, not be BEHIND the drone...
Always thought about it like.. If you leave a helicopter hovering in the same position for 12hrs will it travel with the earth or?
Good question haha
My guess, if he starts the car from rest to motion the drone will be effected but if the car is in motion (uniform motion, better) the drone will have no effect. Like, do jets get effected by the motion of earth?
warrior from the deep web you don‘t know what the theory of relativity is, do you?
Johannes Riebel well infact yes, I just wanted to tell about relative motion and rest and occurance of inertia and don't know how I ended up typing that in the end lol. Never realized that. Thank you.
warrior from the deep web affected*
Johannes Riebel
Not really what the "theory of relativity" is all about.
Johannes Riebel He is right. The drone won't move unless the car accelerates. Easily understandable eexample: you wont be smashed in the back of a plane if you jump in it.
Shoulda just used a tiny whoop instead of putting your lives in danger thats sorta ridiculous with a massive drone. I never stand that close to my drones when flying even out doors.
A balloon filled with air will do the same thing. When you take off it goes rearward because the gas in the vehicle attempts to stay at rest and create a high pressure zone in the rear and low Pressure in the ft (when driving forward). After the initial static friction is overcome, it will go back to where it was.
To prove this inflate a balloon with helium and go forward... what just happened? The balloon went forward because the buoyancy of the lighter helium molecules are moving away from the now slightly compressed denser volume of air in the rear.
Ryan :x He is absolutely correct.
that is a completely different phenomenon
He actually used this example i believe to describe negative wight behavior or something like that
with dji drones the green light blinking means gps mode is on, which means it uses the gps to stay in the same spot. it was staying put because of the gps, not because of physics. when it lost gps signal (yellow blinking for manual mode) and was actually moving with the car during those moments, you can tell it moves by gps because when its "moving" its literally tilting to move to the right spot based off the gps trying to stay still
Me: CREEPER
2:49
The drone geo-location that means it will try and keep the GPS coordinate if the remote has no input.
???????????? Do you know what inertia means right?
Go Wikipedia --> Newton's laws of movement please.
I just hate people who post random comments without even watching the video.......hey I'm not one of them okay
But did you read the whole comment section before commenting this comment?
Abdullah Mallah yeah there were about 27 comments, so I read all of them
To be fair he did ask people to comment before watching.
Wife: can I go do work THATS necessary now?
Should have tried this in the tractor trailer
It would sure just get blown off the trailer.
GMByte Java LOL... an enclosed trailer doofus.
what happens to Newton's first law? Does it apply?
Newton's laws apply in non-accelerating frames of reference. If the drone took off while the car is stationary and the car accelerates forward, then the air will push the drone forward. In the absence of air inside the car or if the back of the car is left open then the drone will appear to move towards the back of the car as the car accelerates forward.
So Newton's laws do not apply with respect to someone in the car but it does apply with respect to someone outside the car.
Rian
true but newtons' first law states UNLESS ANOTHER FORCE IS ACTING UPON IT
now. if he tried this with a balloon it'd be a difference story
but with those propellors, it adds another force to it
i wasn't talking about ACCELERATION
i was referring to the fact that the propellors a providing a different force.
i was referring to the fact that if he drove at 60km per hour and kept an roughly constant speed that the balloon for the most part would just sit there
the balloon thing is simple
"then the air will push the drone forward"
Sigh. Think about how fast that "wind" is travelling. It's not going to to anything. I can't even believe how many people think that explains what happened here.
I imagine it's the shock wave of the air bouncing off the back of the car that prevents the drone from moving all the way to the back of the car as the car accelerates. In the absence of air the drone would hit the back of the car as the car accelerates.
The laws of physics are the same in all inertial frames. So the drone should behave normaly when the car is moving at a constant speed.
Florian if the drone is already flying, and then you move the car, the drone will fly to the back of the car. If the drone takes off after the car starts moving, then the drone will stay in place.
When the windows, doors are open and there is air flow within the car, then it's hard to predict where the drone will go.
Correct me if I'm wrong
Siyuan Zheng Your, not entirely of. But It's important to differentiate between accelerating and moving at a constant speed. If the car is moving at a constant speed "v" the drone will behave normally. Like when you are inside a train if the train is moving at a constant speed you can jump and will land at the same place where you jumped off. If however, the car is changing its speed (accelerating or decelerating) then it gets a little bit tricky.
When you accelerate, there is a "pseudo-force" that pushes most things to the back of the car -- this is the feeling of being pushed back in your seat when you accelerate and also throws you against the seatbelts when you brake suddenly. This is not a real force -- it is an effect of your inertia (your tendency to remain in the same state of motion) hence the name pseudo-force. Pseudo-forces are present anytime your frame of reference accelerates; They even affect the air in your car -- so when you accelerate, the air tends to move back a little -- not so much that people on the front seat suffocate, but enough that the air gets a little denser (and higher pressure) the further back you go. So you would except the drone to move back when the car is accelerating. But i don't think its that easy cause the pressure is increasing in the back of the car so I am not entirely sure how the drone would behave but it will definitely move^^. And yes if the windows are open it would be very hard to predict the movement of the drone.
Florian When you accelerate its not that simple. More dense air (cold) close to the floor will move back and less dense air on top will move forward while accelerating. Plus this is a stupid experiment to be done with a drone since 1. a drone is expensive 2.it has sonar and a bunch of other sensors that ruin your results.
Florian You can't say that until you know whether this model had GPS in it or not. The expensive drones are designed to hover in place using GPS as their frame of reference. You're only thinking of momentum.
MrCoffis He did say he disabled the crash avoidance feature. I'm guessing that is what you are reffering too.
If y were in high school you should knew the awnser by now and you wouldn't have to watch this 😂😂
What if you fly a drone inside a spaceship?
I always wondered that (actually just now)
Pro Player 1⃣ 🤣
King of Random did that.
I assume you'd have to have modified software in the drone, in order to have controlled flight.
As I don't think there would be anyway to get it to descend normally.
Pro Player 1⃣ I know that a fly cannot fly inside a vacuum so i would say neither could a drone
I want to love banggood but my first expensive drone arrived broken still waiting for response 😣
Hopefully I get good solution it was hard moving it through customs they dislike fpv stuff 😔
SAAD HERO that's sucks hopefully they help you
I recommend sticking with physical stores for expensive stuff
+SAAD HERO that sucks, they seem to be helpful on my end but it is probably because they send me products to test. Hopefully you get that worked out. I prefer amazon but sometimes banggood is much cheaper and has stuff amazon doesn’t.
The Action Lab they are better then Amazon on deals and more drones
I guess they most test everything before sending it to anyone to test
So far they offering a 30$ refund
The price was 299.02
I don't know if this good deal feels not what's your opinion?
SAAD HERO what was broken?
Austin C one aileron of the plane were broken it didn't affect lift so I tested it I didn't fly the plane flys for few seconds then pitches down
Even in auto pilot mode so flight control unit is defective from what I see
My prediction is the drone will go to the back of the car. The way I see this is if a drone is on the floor, the car would be carrying it along. In this case the drone will be in free space and not moving at all. The car on the other hand will be moving. The car will technically be moving away from the drone.
The air inside the car moves with the car. Therefore the drone stays is place.
That's not how it works lmfao... So you are in a plane going 500mph you jump and you land in the same spot give or take... that's because you were already going 500mph, so if the plane could go 0-500mph in under the time it takes you to jump and come back into contact with the plane floor... you think you would accelerate with the plane? lmfao no. the 500 mph wind will rush around you as you jumped and you would slam into the back of the plane as it hits you at 500mph the same rules apply to the drone just because it's flying it doesn't mean it voids physics.
It's not in free space, it's surrounded by air in a relatively enclosed space, when all the windows and doors are shut. It's possible to accelerate the drone to match the car's speed using the air surrounding it, if you keep a really low rate of acceleration. Air obviously moves around though, so there's no way to have instant control over the drone's acceleration or deceleration in the directions that aren't controlled by propellers, or to have it remain in the same spot it was in when you began to change the speed of the car.
X III the reason you don't hit the back of the plane is nothing to do with air pressure. It's because when you jump you are also moving at the same speed. Relative to the plane you are travelling 0mph.
Yeah I know that's what the first half of my comment said buddy!:)
The same thing when You toss a pen or other small objects inside an airplane in front of Your face
I always want to jump inside an airplane and seeing if i throwed to the back of the plane but I was scared because there's officer so I don't do it lol
Did he turn off gps mode?
+TheBelgianWaffl _ Gaming yes
The Action Lab doesn’t the mavic have downward facing cameras to keep track of its location even without gps? Or did you turn off that too? Don’t know how it is with the mavic but you could try doing it in the ATTI mode
There's no way to manually disable GPS mode on the Mavic
Jason Lane there is
there really isn't
