- What's a frame of reference and the two types? How can you tell?
Watch and find out. This leads to a conundrum Einstein had about how light behaves in different frames of reference and led to a radical new way of thinking. That will be covered in subsequent videos

boss level--- teaching while driving
I got what I needed and have to appreciate your work and ur passion to explain physics in our daily life.... Satisfied ❤️😊
The whole video, I was worried if that ball was heavy and was going to knock him on the side of the head.
Thank you for making this video. It has inspired me to keep making more videos of my own. I am thinking about how I can make a worksheet for my VCE Year 12 students using this video. Very helpful.
Hello! I noticed you hadn't posted in some time. I understand that making videos can be challenging but I wanted to share my thanks and view that regardless of immediate feedback, the important thing is that your contribution exists. Learning to me is an experience, I'm always fascinated by the fact that we can read the same sentence 100 times and possibly derive better/different understanding each time. I think teachers/teaching follow the same phenomenon. Sometimes you're the person someone needs in order to provide the perspective that "clicks". Your comment here has lead to one more subscriber/viewer. Thank you for your contributions in elevating our minds
Thank you, sir! I needed a good explanation I wasn't really understanding it before.
Glad it helped
I totally understood what reference frames are. Thanks for the video.
your teaching is like balancing two pens on each other.....
really great explanation sir!!!!!!!!
Glad I clicked on this video. It helped me understand it better. Thank you so much, Sir!
You’re welcone
Very nice. Will use it in my classes.
Thanks a lot really, I enjoyed the discovery ❤
Not all super hero’s wear capes. Thanks for sharing!
It was really helpful
I know Victoria when I see it... great video, thanks mate.
Very nice video
Hi Paul. Great explanation. Indeed. However, the physic as a such wouldn't be a physic without surprises. There are several things that are not fit the observation of relativity. One of them I want to mention here is the fly by anomaly. There is an interesting work: Probing the Flyby Anomaly with the future STE-QUEST mission, written by Jorge Pa ́ramos and Gerald Hechenblaikner.
The abstract: Abstract In this study, we demonstrate that the flyby anomaly, an unexpected acceleration detected in some of the gravitational assists of the Galileo, NEAR, Cassini and Rosetta spacecraft, could be probed by accurate orbital tracking available in the proposed Space-Time Explorer and Quantum Equivalence Principle Space Test (STE- QUEST); following a recent work, we focus on the similarity between an hyperbolic flyby and the perigee passage in a highly elliptic orbit of the latter, as well as its Global Navigation Satellite System precise orbital determination capabilities.
And, I have to tell, it is an excellent thing by itself. The theory of relativity works, relativistic corrections for GPS are en excellent example of it, but simultaneously, does not work as it should using article above!
What solution techniques are useful by changing frame of reference
Like centre of mass frame you can solve collision problems
Please generalised this
Thank you. I had a better grasp of the topic when I watched the video.
Great
the different slides of road acting on the tiers causing it to absorb a different forces form each tier which they developing an small mechanical vibrations in term they cause the ball to move slightly in different directions
*high school physics explained*
Me in uni physics : 👁️👄👁️
great sir
Great job at explaining a difficult concept.
Thanks
sir, if two references are accelerating in same acceleration in respect of a inertial reference... can those 2 accelerating reference can tell they are non inertial in respect of themselves or they are inertial in respect of themselves?
I hope they are stationary in respect of themselves
Just when I had had enough of incompetent lectures on relativity and inertia frames. Nice teaching Sir🙏🙏
So non-Inertial as in moving without there being an applied force. Got it 👍
2:45 beautiful evo passing by
What if there were a paved road that encircled the Earth at the equator. You get in a car with a hanging ball and begin to accelerate down the road and of course the ball swings back. Now repeat the experiment but instead of accelerating the car you accelerate the Earth's rotation beneath the car. I assume that the hanging ball will not swing back in that case. Would that be an effective experiment to determine if you were actually moving? Wouldn't the only apparent difference between the two cases be the state of the hanging ball?
Very helpfull
Glad it was.
So what is the importance of havinh frame of reference in the study motion?
Good question
In essence it forms the basis how we measure. We always measure from the observers perspective. Their frame of reference. An example will help. I child a ball upwards on a train platform as two trains pass going in opposite directions. What the ball appears to do from a passenger on each train as well as the child will all be different but all are correct. They are relative to the observer. So if I want to compare what they observe then I need to know about what each frame of reference is doing relative to me and each other.
An understanding of frames of reference also forms the basis of understating Einstein’s theory of relativity. I do suggest looking in my videos on that.
Are you telling me, that if I was in space and if I was rotating/spinning with a fixed period, I would not know/be able to prove that I am spinning?
nice sir
Thank you
Thank you for that information sir, it helps me a lot. But I am curious about the Sun hehehe, is the sun is an inertial frame of reference?😅
Strictly speaking no. The sun itself is moving around the galaxy in orbit and so locally it can be seen as going at a constant velocity but like all stars are actually experiencing centripetal acceleration.
@@PhysicsHigh ahhhh....thank you sir.😊
24,the question about the Atrio ventricular valves was not specific
✨✨✨
NathanOakley1980 did a live review of this video. I'd be interested in watching your reaction to said video and the legitimate points/questions raised.

I am confused and no one will help me. (1) I am told there is only ONE type of inertial frame of reference. (2) meaning if i do a physics experiment in ANY inertial frame i will get the SAME RESULTS no matter what inertial frame i am in (3) Disregarding earth spinning and angular momentum (acceleration) I am told earth is an inertial frame. (4) I am told being in outer space at a constant velocity is ALSO an inertial frame. OK THESE STATEMENTS CONTRADICT ONE ANOTHER !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Because if that were ALL true then that would mean that i could do physics experiments in outer space (at a constant velocity) and then do the SAME PHYSICS EXPERIMENT on earth and get the SAME RESULTS. But that IS NOT TRUE. THAT IS A LIE. If i am in outer space(at constant velocity) and i hold a ball out and let go of the ball with out throwing it or pushing it in any direction the ball will just float there. But on earth if i do the SAME experiment the ball will fall to the ground GIVING ME A DIFFERENT RESULT. So there is either more than one TYPE of inertial frame of reference and each type has its own physics OR earth is NOT an inertial frame of reference. SO WHICH IS IT ???????????? Why wont any one answer me???????
Coffin dance for this man
What if a car hits you
Which one will more dangerous inertial or non inertial
CHALLENGE to anyone who thinks earth is in an inertial frame of reference and "free falling" objects are an accelerated frame of reference.........
Let us say you are in an elevator WITH NO WINDOWS on the moon so there is no air resistance to falling. And the rope holding the elevator breaks on the 500th floor and you and the elevator starts "free falling". And lets say i am in a space ship in outer space moving at constant velocity. WE BOTH WOULD SAY I AM IN AN INERTIAL FRAME. Now you say "free falling" is an accelerated frame of reference. So YOU ARE SAYING we would be in DIFFERENT frames of reference......you in an accelerated frame and me in an inertial frame. SO YOU SHOULD BE ABLE TO PROVE IT EXPERIMENTALLY...RIGHT??????????????????????? Cause if we do identical physics experiments there should be at least ONE experiment where we get different results.....right. WE BOTH AGREE WITH THAT RIGHT?????????????? So tell me what experiment would you do to PROVE you were in an accelerated frame of reference while you are "free falling" inside your elevator???????????? If you can NOT think of an experiment that would give us different results then you must admit that "free fall" is an inertial frame because WE BOTH AGREE THAT me in a space ship in outer space moving at constant velocity is AN INTERTIAL FRAME.
And guess what. If you .......while in your "free falling" elevator would hold a ball out and let go of the ball with out applying any force to the ball. Guess what the ball will just float and not move relative to you. Just like it would for me in my space ship. So that would be the same result. What experiment will you tell me about that gives different results???????????
Imagine if he started to accelerate really fast and got a ticket.
"Officer, we have a different frame of reference. In mine, I was stationary and I can prove it in traffic court."
NathanOakley1980 sent me, he was responding to this video.
Lol does he think he debunked physics now?
Nathan Oakley can’t count to 20 without removing his shoes
Why don't you watch the video and then reply.
"Condemnation without investigation is the definition of ignorance".
@@djthunderfoot1879 who you talking too?
People will get angry at someone for speaking the truth, rather than being angry at the people who have been lying to them.
"I'm stationary relative to me" - this is called self reference and is not about relativity.
I'm great because I'm great, I'm bad because I'm bad - is not about relativity.
is the ball full of water?
Yes though not full. It’s one of balls from Veratasium’s videos.
Great video dood, sorry about the 2 or 3 lunatics that are about to enter your chat just block them brah stay far far away from their nonsense 👍
shame about the bumps, film this again on an empty train!!
I thought about this. But empty trains are rare and free time is rarer. You’ll have to come along and help. 😉
@@PhysicsHigh and play robin to your batman lol
@@craigrussell4105 doesn't robin have COVID 19?
@@James-le8gd dunno, but i bet theres lots of empty trains now
And as a consequence of your understanding of the frames of reference you can know if a time lapse camera and a drone hovers over it for three hours and it stays in place as the stars move ...... That earth is not moving the stars are. Welcome to flat earth Nathan Oakley 1980 sent me.
Watch as i look at the road while looking at the camera *crashes* the moment of impact was a demonstration of inertia.
I understand the desire to teach, but no need to endanger your and the lives of others around you :(
Thanks for your feedback. You are right that looking at the camera can be distracting, and can be a risk. This is my first car video, and probably my only one since it directly relates to the topic. However, if I did another I would certainly rethink how I would film it, if at all, whilst moving.
Parking lot, abandoned airport.
You can put up tall cardboard on the bed of a pickup truck to make a box. Duck tape it and secure your bowling ball above it. If the cardboard was painted black with no holes, you wouldn't be able to use the background to view movement.
In your current video, i used my fingers to block your Windows. Unless you said "I'm not moving" or "I'm moving," i couldn't tell once i blocked the Windows :) (well, unless you turned ofc)
P.s. Have you done a video on "what rolls down faster: Hollow cylinder or solid cylinder?"
Good idea. Though I need a truck 🤓
Rolling solid and hollow rods? No not yet but good idea. At some stage I plan to do.more rotational mechanics and esp moment of inertia so that will fit right in.
Box, rolling cart, camera, string, fishing lead weight. No truck, no problem 😁
There was a professor who did the hollow vs solid rods rolling on a slanted surface on RUclips. His explanation went over my head, i look forward to seeing yours.
“Hire” a driver.
There’s some flat earthers here ignore them
A really dumb flat earther sent me here, lol
.oneffunes. Ezekiel 1:18 As for their rings, ( The beginning and the end the first and the last ) they were so high ( They transcend thought. Rom 11:33 past finding out ) that they were dreadful; ( Man fierce what he Doesn’t understand ) and their rings ( The beginning and the end ) were full of eyes ( The first and the last ) round ( The circumference of the beginning and the end ) about ( In the diameter of the beginning and the end ) them four. ( The beginning and the end the first and the last. )
.oneffunes. Creation is relevant to the structure of God, and it’s not the other way around. It doesn’t matter how you move or where you are in the structure of God, the center is Equal to the circumference and in it’s diameter, therefore if you are moving through the structure of God, it doesn’t matter where you are or how you move I AM always stationary, I Am the ultimate inertial frame of reference in and inside my creation. Case in point, If you were moving through creation In a car and I was standing on the outside of that car as the creator creation would be passing you but I would be static relevant to you and you to me the law of physics would be the same for you! But I would transcend The law of physics because my center is equal to my circumference and diameter.
