Introduction to centripetal force | AP Physics 1 | Khan Academy 

That picture is epic. Im sure Sal has unknowingly just created a super hero.

You inspired me to start my own RU-vid channel for tutoring. Keep doing what you're doing Sal!

Sir you should also have a Degree in Painting🤯❤️

Nice way of showing centripetal acceleration by combining velocity vectors at 2 points!

Oh man I’ve just finished my exam on this subject

Great illustration! Thank you

You know buddy, I'm a high school dropout with a GED who is interested in physics. I actually for the most part understand your explanation concerning the inward force especially at the end. Thank you!

keep making these videos

ITS MAKING SO MUCH SENSE!!!!!!!!!!!!!!!!!!!!!!!

Sal please make calculus based physics

Thanks a lot man...Explanation is clear

Can you calculate the difference in centrifugal force in the North Pole compared to the equator, thanks?!

Thank you

What about a tetherball? The pole is not a human pulling the string inward. And the rope gets shorter as it goes around. How do you explain this kind of centripetal physics?

This is not yet in playlist right?

May i know what software he used to do that kind of drawing? Blackboard style of drawing

but how do we get magnitude of acceleration with v2/rvformula when the change in velocity's magnitude is zero

Not even on the subject yet but it's very cool

Nice drawing

Nice

But why we have to shift the velocity vector???

"now one question you might have been wondering..." newton's third law newton's third law newton's third law "...newton's first law might be nagging at you" oh.

"trencipital"?

Dope
