- This video was made for the Breakthrough Junior Challenge. It is a short video on orbits and orbital mechanics. This video was made with the intentions to educate and entertain people on a subject that is normally hard to understand and relatively boring. Enjoy!
Credits are at the end of the video.
>Made 1 high quality video.
>Went on an indefinite hiatus.
>Refuses to explain why
>Absolute chad
i can nearly assure you that this was made for some college class.
@@NothingRandomit's made for a challenge. Check the description.
This is a great tutorial for Kerbal Space Program.
The rockets aren’t wobbly enough
And SFS
I honestly couldn't take my eyes off of this video for all 8 minutes and 58 seconds. You have done an AMAZING job! Your humor is on point :D & this video made me forget that I was actually learning. Job well done, Nick! Loved the animation. Good luck & I look forward to more of your videos.
An escape trajectory is typically an hyperbolic orbit. A parabolic trajectory means that you "exactly escape" (leaving no remaining speed, or in otherwords you escape at t = infinity).
+pulli23
That is right. I threw parabolic orbits out there because students tend to learn about parabolas well before they learn about hyperbolas, and the hopes are that they could visualize a parabola in my video, because that is the basic path. I'm just trying to get the concept down. The idea is that there is capture and an escape (two different points), but yeah I probably should have a note in the video for that.
@@NicksterChannel hello nick,hope you’re doing fine.I have a graphics tab(GS640)....Will download flash....can u direct me to a beginner guide.Thanks
This is very very well made, possibly the most entertaining one among the finalists.
Possibly the most educational 8:58 minutes of my life, was not expecting to learn so much about the different orbital manoeuvres. You the man Nick ! You should make more videos about satellites and space !! just subscribed :)
This is amazing!
A lot of people think orbital mechanics is super hard, but you proved you can explain it to anyone.
this is the single greatest thing I've ever seen. I finally understand the meaning of life, what I'm going to do with my life, and quantum physics now. thank you, all my success is due to you good sir.
+jhicks97 But there was no quantum physics in this video!
I so wish you would have made more of these…I’m working on learning orbital mechanics and this was one of the most fun and easily understandable videos I’ve found. 7 years ago, the beginning of learning genius…bring it back and make the rest 🙌
i just love the ksp burn sound effects
you should make more like this, lol, epic
So I just found my favourite video on the internet. Feel like making another one? Cause this is flipping amazing
You need to do a lot more of these. It was fantastic. Thanks.
Thanks for a really good video that explains a lot of concepts really simply in a compact way. Most other easily-found RUclips presentations about how orbits work are written by people who don't *actually* understand orbits, rocket launches, and the like. I might quibble with the way you glossed over the difference between parabolic and hyperbolic orbits, and I'd suggest talking about Hohmann transfers before bi-elliptic transfers, but that's something for v2.0 of this video. :)
Best video there is on orbital mechanics! Good job
Oh my god. I just understood gravitational assist. Mind blown. Thankyou
Thanks for characteristing Hohmann and bi-eliptical orbits for me. And clarifying the effect of radial burns. I thought that was what happened, but it's nice to see it laid out.
It's too bad you didn't make any more. I'd gladly watch more of them!
You explain this better than my University Professor.
Very well explained with clarity like teaching to the nursery with good animations. Thank you so much.
You don't see a video like this one every day. DON'T STOP DOING IT! I'M NOT ASKING YOU! I'd love to see another one :D Thanks.
From this video I started understanding orbital mechanic.
You should do more videos, people need them
I love this video, it's my go to video to send when someone asks about orbital mechanics
I loved this video. Honestly this video is by far the best of all the videos I've seen. Not even kidding. Your engaging, fun, and the animation looks professional and crisp. You explained your points well, you beginning was outstanding, and your animation was really up there with Daniel.
If you won, I wouldn't be surprised.
I'm taking astrophysics as a physics major. Your ball and racket example just cleared up so much and showed the Virial Theorem in action.
Virial Theorem: 2 + = 0
From this, we can derive the vis-viva equation which you show at 2:53
Just remember your conic section equations in terms of eccentricity (e) and the following:
Circle: e = 0
Ellipse: 0 < e < 1
Parabola (escape): e = 1
Hyperbola: e > 1
Finally, remember that gravitational assists work best at the lowest latitudes given tangential velocity is greatest at the equator (this is actually a reason Roscosmos was at a disadvantage to NASA in the space race; tangential velocity can be found with v = Rωcosψ where v is tangential velocity, R is the radius of Earth, ω is the rotational velocity of earth, and ψ is latitude; you can see that v is greatest at ψ = 0).
Wicked awesome job, Nick! You took on a lot in that and did a great job explaining a complicated concept!
Very well done! I truly enjoy your art style and animation. Good luck to you sir!
Compliments:
- I really liked the way you described the vis-viva equation at 2:58. I was always confused on how burning prograde will extend apoapsis until I realized that when you applied an accleration that increases the instantaeous, tangental velocity the SMA will increase according to the equation
- Cool way of explaining. I used the game Spacefight Simulator to explain orbital mechanics and also joined the breakthrough junior challenge, but it is NOWHERE near your quality.
Suggestions:
- Mention Kepler's second law when describing speed at the perapsis and apoapsis. Since the spacecraft sweeps out equal area over the same time and altitude at Periapsis is less, the spacecraft must travel more distance at given time therefore it moves faster and vice versa for apoapsis.
- I actually broke space navigation rule 2, when I burn early, a little change in velocity changed the position SO MUCH that I overshoot the target, so I had to burn later for precise control. Lol
- At close distances, orbital mechanics is negligible, that's how you dock in Spaceflight Simulator(although I never succeed)
- I actually burned radial once to "rotate" my orbit. So basically, I failed Hohmann transfer and my apoapsis didn't intersect my target orbit, but I have to reach the target orbit really soon. So I burned radial to rotate my orbit and intersected the target orbit a few meters left. Whereas if I did another Hohmann transfer it would take too long to reach my target orbit.
Question:
Can you explain the concept of infinity during a parabolic orbit? Thanks.
That was a huge amount of info in such a short vid. It was also really easy to understand. Cheers.
I just watched a 1.3hr long video lecture from NASA on this subject that gave me less information than your
thank you for this amazing video! I have an exam in the days ahead and I was sick and tired of studying boring lessons. It helps me to understand these topics better.
i had a hard time with my Physics teacher on this, and this goofy video cleared up a lot. Your work is amazing.
This is a thing of beauty. Make more please.
Hats off to you for using flash!!!
Awesome video
Blissfully explained
This is the greatest thing I’ve ever seen 😢
This channel deserves more subs and videos. Can you now make a video about how a satellite can catch up with another satellite that is ahead of it in the same orbit?
I busted out laughing at least a couple times during this, oh and I also learned about orbital mechanics. Not an easy feat my friend. Keep making these and I'll keep watching.
I dub this video the best of them all for the initial understanding. Now all I have to do is keep digging youtube for some technical gravity assist videos.
You've summed it up really good. Excellent job.
I see a very clever 7 year old video - I subscribe. 🤷♂️
this is glorious. please do more!
Funny, interesting and knowledgeable. Good videos. Keep it up.
Really great video sir!!!!
Wow, congraturations on being a finalist Nick. Oh yeah, Braden is me.
Thank you for the video.
Actually using this video for something important
This awesome, thanks for making this
Velocity of ship approaching and leaving the Moon during fly by is not equal (by modulo). Gravitational slingshot effect changes the speed, not very much but.
Wow very well made!
Your have done a great video, that is Most likely the best Video about Orbital Mechanics Out there it would bei great If your do Mode Videos Like this one
What only 5 videos whatttttt dudddeeee you should make more it’s amazing!!
Nice good Nick
Great Video
this is gold
Nice! Keep going
very nice!
please do more of these !
Great little video bro!! Keep it up . . . . MAKE MORE!!
Thanks much!!
:-)
Greeeaaat!
Make more pls great vid
Draw is so cute.
I learned all this empirically at KSP.
so awesome! what software did you use to make the animations, i'd love to incorporate that sort of thing in my videos.
I used Adobe Flash for the animation. A graphics tablet is almost necessary as well, but I was able to make that with the smallest and cheapest Wacom Intuos. You don't need anything expensive!
Watch til the end.
this is brilliant
make more man!
That. was. awesome! I was wondering why you seemed to be ignoring that the moon was moving and that by the time your rocket reaches the moon it wont be there. Then you introduced Space Navigation Rule No. 2 and I started cracking up.
MAKE MOAR.
That was perfect, thanks!
This was awesome LOL
06:08,
Even though i saw it coming, it was still funny as fuck xDDD
Super can understand easily
You need more subs
GAWD EPIC
So informative ...!!!!!!
Wait, should apogee and perigee be counted from the center when doing calculations?
Just asking, what score did you get? Your video was outstanding. If it doesn't get at least a 85. I'll hunt down your judges.
You're da man!
This is some quality shit
This very useful for space engine :3
Why there is only one video?
You said that thing is for another video. Where is that video? Where is any video?
A couple more of these and I could work at SpaceX.
4:33 I was struggling to understand how firing away from the Earth moved the radius of the rocket's orbit, that is until I saw the arrows you drew. The orbit vector combined with the vector of the rocket firing orthoganally to the Earth creates a resultant vector that is tangent to the orbit. The path the old orbit moves to the new orbit would be the magnitude of the rocket's thrust in the direction of the new orbit. Is this correct?
+Idlehampster
The most efficient way to "make a turn" is by firing at a 90 degree angle from the orbit vector, so as the vector turns, the rocket will have to as well to maintain that magic 90 degree angle. I know the change in velocity (delta v) needed to redirect that rocket's path would be equal to the rockets total thrust over that time but that is just conservation of energy. In summary, I have no clue how to verify your second statement.
The orbit vector combined with the thrust vector would produce a vector tangent to the new orbit path, in a perfect world (because rockets can't change direction in an infinitely small amount of time).
DISCLAIMER: This might be wrong. I have no degree, I just like to read.
If I eventually figure it out I'll let you know.
-Nick
What book(s) on the subject would you recommend? Also, do you know any book that's on space engineering (aka astronautical engineering)?
It works the same as a gyroscope. With a spinning gyroscope, if you blow on the side (anti-normal), it does not tilt down toward where you blew. It tilts the furthest point in the lateral direction. The lateral points of force occur infinitely around the object you orbit which is what makes them so insanely stable (barring tidal forces).
I was using my earphone in a high volume... Just think of my condition at the end of the video..
1:07 - and this is why Daniel has depression issues lol ;p
dis shit cray m8
Remember this all exists because of GRAVITY.
you're underrated lul
7:46 The speed of the Moon should be doubled.
I can't feel my hands
No, if my brain explodes, that's it, I'm suing.
MORE
from ksp
HEY NO I NEED MORE KNOWLEDGE
COME BACK
slow down on the gravity assist bro!
my brain did exacrtly like in the video🎆
make
more
VIDEOS
Heh. 1:30 "Asteroids"
ARE U GOD
SPACE MOOSE
5:16 *AND THEN YOU MISS, BECAUSE THE MOON MOVES TOO*
Kerbal Space Program
Quite interesting and accessible, but sometimes all the sound effects and/or too much jokes take the mind of it. Thanks though ! ;)
6:07 lmao
