This video is very helpful. Please keep posting videos!

This is the clearest and most easy to understand explanation of what 'frame of reference' is. Keep up the good work, subscribed! :)

Just found this channel, looks awesome, going to binge watch it. Thanks for making videos like these!

So if I decide to drive home drunk one night, and crash into a pole, I could say the pole ran into me in my inertial frame of reference? #physicsoverlawschool

Great video, very clear. I like that you take the viewpoint of the viewer who doesn't know physics already. Thanks!

Short and informative !! please keep doing more videos :D

You are awesome. Thank you so much, because thanks to you I was able to do my astronomy homework.

That's pretty awesome, good explaining.

Keep posting, you're great :)

thanks I'm not a physic student just a fan of relativity this is one of the best educational materials on the subject I'm grateful

Excellent video

You're really good! One question though, this means that when we jump inside a bus, we don't crash into the back because we were originally in contact with the bus (in it's reference frame), right? So if we jump from the ground and a bus suddenly teleports itself to our position while moving, we WOULD crash into the back, right?

Awesome video

you rock!

There's the counter-example of sitting in a parked car and feeling like the car has suddenly started moving because the car next to you started moving.

GREAT VIDEO :)

I'm in traction. lol Great content... subbed!

ok, what if there is fly in the moving bus that is not jumping but kind of stays in the air within the bus, does it have an impact?

If you would be in a moving box and you would fall over due to a change in speed at which the box moves (or starts moving), you wouldn't be able to judge whether it was accelerating or slowing down either as you would not know in which direction it was moving in the first place... right?

1:48 so if i go onto a bus where that is somehow true then I couldn't get motion sick?

What will happen if I jump inside the stationary bus and the bus starts moving instantly after I get off the floor of the bus?

What about time dilation? Can you use that to see who is moving faster?

How does this explain the universe different groups, like galactic clusters, galaxy, sun, earth... Moving in DIFFERENT DIRECTIONS?

my brother: of course not, if you were standing completely still, time would go infinitely fast

What if I was near to someone and we both had toy drones we hovered the drones 2 metres above the ground then a lorry reversed with its back door open till my drone was 50% inside the back of the lorry, the doors were then closed and the lorry drives forward , what happens to the drone???? can't seem to get this out my head I'm sure the answer is obvious😂

Are you from Waterloo?

So the bus is moving at a constant velocity in a straight line, but the earth isn't. Is earth still an approximate inertial reference frame, because the velocity changes so minimally on our scale?

But when you are standing on the bus, you actually have no motion becoz you don’t spend any energy, how could you continue your motion?

Is the earth really spinning 30 km/s? Or is it stationary

What if you are moving close to the speed of light and you throw a ball with a timer on it and throw it forward at close to the speed of light and have a friend do the same thing who ever has a lower time must be moving slower.

Location: Waterloo, Canada? That's where I live...

Let's say the heart has a cone that perfore it vertically from a part of the globe to the opposite one as line, or better a drinking straw.Let's say I head dive with my front head and that theorically there is not any impedement to go to the other corresponding part of the globe. What happens at time x when I arrive to the other part of the globe, will i be with my head going out from the globe, I guess as somebody that just opens a ground trap door and come out from the ground. So the question is in which moment I will realize that I am not as a yoga head down position going down, but actually I will have the feeling i am going up, not down!

Inertial frame of reference... Frame of Essence... Is that coincidental or does it relate it some sense?

But if the bus had no barrier (walls)?

So how can we prove the earth is moving through space?

got kicked of the train after i shouted at the ticket controller that i wasent moveing and thus refused to pay, he said of course i was. i said "prove it"

3:00 and the Milky Way galaxy is "moving" at about 2,000,000mi/hr.... seriously look it up...

Well, an observer system is always at rest, all other systems is always in motion.

4th!

everybody has their version of truth -

This requires constant and straight line of acceleration/movement, and no gravity for a prolonged period of time (something no one has tested). If the initial acceleration is strong enough to overcome friction you will end in the back wall of the bus, also if it turns or brakes. All what happened is that momentum requires contact for transferring, so does inertia (no movement). The CMB tells us we are not moving, we are the axis. So we have a stationary reference point. Quantum entanglement clearly shows there are things faster than light and an interconnection between everything beyond our current testing capabilities, a scalar field. But we don't want to call it "aether" for not discrediting Einstein's uscientific relativistic crap. Lightspeed is just a rate of induction, our technology and nature are limited by design by this because we are "blinded" by our outdated atomistic particle philosophy and our "scientific methodology". We are "Field Theory Impaired." The universe is all about fields, frequency and coherence/incoherence.

if the universe is limited, then the edges of it are standing still

i jumped on a moving bus 10000000000000 times

Why don't we just use _one_ measure for speed? Measure everything against whatever we used to measure the speed of light (or anything, I don't care, just pick a standard). That way, you could disregard dumb, unimportant points of reference, like the bus, or even the ground. Just have ONE point of reference for everything, then we'd know the "true" speed of things, or at least be consistent enough that annoying word-games like this don't happen. The damn guy in the bus IS moving, so is the guy on the sidewalk (just MUCH slower), so is the grass on the ground next to him. Likewise, the ball (from SR1) is going at the _same_ speed regardless of who sees it, it's the perspective of the observer that is changing, not the speed of the ball. The speed of the ball can only be the speed of the ball, the problem is we don't have the language to accurately describe something independent of human perspective, because we're a far simpler ape than we credit ourselves for. I wish Wittgenstein weren't dead, I'd very much have liked to talk to him about language.

I am unsubscribing from most science channels and subscribing to yours a million times.

please weigh into the current flat earth deception, you seem able to explain complicated concepts simply, like i was 5 lol but man these flatearthers need a shake up PLEASE!

thanks for the disclaimer, wouldn't wont folks hurting themselves cause u gave them the idea.. food for thought though. try jumping out this bus while its moving and see how you fair.. hope you paid ur fair/fare (god bless English).. imagine the perspective of you friend as he watches you look like an idiot.. wheres all the light in this matter? all this could be explained but who had the time? really who has the time?!!!

Try playing Super Mario Sunshine, it violates that law.

There is no stillness, stillness is non-existence. Matter and photons are motion (energy) on the aether. No motion on the aether = no energy = no photons or matter = nonexistence.

Einstein crazy crap... More Sci -fi staff , than true science...😂
