Relative Motion and Inertial Reference Frames

Come on sir go back 6 years😂

i love you sexy bearded man

Such a good explanation! Your animations are so easy to understand. Thank you❤

I wish someone could explain how this relates to the portal paradox. I am confident that the portal moving towards a cube is the same as the cube moving towards the portal, but I just don't know how inertial frames of reference relate to environments on both sides of the portal. Why is it that an object only switches inertial reference frames after going through the portal?

is relative motion rectilinear motion?

Videos like this deserve a love button. Like just doesn't express the gratitude.

But initially you said that the observor sees the ball taking a parabolic path because the ball had all the horizontal velocity(of the train) and then later on you say that the ball and the person throwing the ball up dont undergo motion but their surroundings do and hence the ball falls vertically downwards and has a vertical velocity only, kindly clear my confusion.

Really appreciate how you put in so much effort in the animations to make stuff way easier for us 🥰

Seriously..mind blowing explanation 😀

Visualizations are very important in learning. Thank you for the animations - they drilled the concepts home.

professor Dave... you're kinda awesome

I am speed. I move at 230 km/s.

Thank you so much sir for giving me a big scope

You are amazing.

I really like the element of history included in teaching to show how humanity discovered something abd how we know it to be true . Without understanding history certain parts of the present are not comprehensive. I recently watched Veritasiums video on depressed cubics and how to solve them

You just explained the same concept in 6mins that took my physics teacher 3 months. It was so simple to understand?????

so the fastest man is not faster than my 98 years old grandpa

The ball in the train business. This is what I don't get. It seems that the ball in the box-car frame of reference is traveling a shorter distance than the same ball from the rail side frame of reference. Maybe I get it now. Each observer has a timer of the throw. Both clocks will read the same time. So the rail side observer sees the speed of the up and down motion plus the speed of the inertial motion.

Up, up, up. 'No different in terms of absolute velocity.' I thought the whole point of this video was going to be there is no absolute velocity.

Up, up. That last one, the milky way galaxy moving through the universe at X speed. Relative to what?

What can u say about Hilary Andales'

Relatavity & the Equivalence of reference frames.

You mean Europe caught up! In Asia they already knew all these things before any of these so called people

Thank You

nice from India

🦧

Everything is speeding on planet Earth but in reference we don't appear to be moving

I like how the video isn't long

Thanks for this! Great content!

if the earth is rotating on its own axis . is it possible if the plane will fly up and get steady above for 24 hrs without moving in any direction, will the plane land in a different place on earth?, or will the plane land on the same place? pls answer. and justify yuor answer. TIA

The beginning is a Universal Meme 🤣

u the best ever!! ❤️❤️💋🤸🐬🙌

He looks like Indian actor Ranbir Kapoor

CK sir jinda bad 🤣🤣❤️❤️❤️❤️

thank u dave

thanks so much for this! back to the textbook reading now that I understand this part!

What would the free body diagram of the ball look like when it is in the air (when thinking about the example with the train)? Is there a horizontal force that acts on the ball in the direction that the train is also moving?

Excellent explaination 🙌

Is this a satire site??? It has to be satire if people believe this.

Why is he mansplaining physics to me 😭😭

Great video.

Small correction Gallaeo didn't get in trouble with the church for saying the earth revolved around the sun. He got in trouble when he tried to teach that the moon had nothing to do with the tides on earth, which we know to be false.

(My church still should have stayed out of the matter, but the point is that he didn't get in trouble for teaching a theory about the sun but for teaching an incorrect theory about the tides as truth.)

Nice introduction I love it

nice explanation , thanks bro

Thanks albert newton

Myth revealed

THANK YOU

Life will be less tricky if you accurately define FRAME.

Dear man I appreciate your work, I would love if you would make a video about energy in reference systems

Thank you Professor Dave!

Professor Jesus Christ,
Holy physics !
