Centripetal Force and Acceleration Intuition

[thunderboltkrish]

simply perfect intuition

[balletboy94]

there is no such thing as centripetal force! come on thats basic physics -_-

[xJellystix]

@balletboy94 No, there is no such thing as centrifugal force. Centripetal force does exist.

[zjak8]

@xJellystix There IS such a this as centrifugal force. It arises when the observer is in a rotating frame of reference. The rotation of the reference frame makes an equation of motion for a particle more complicated because there "appear" to be forces on it causing it to rotate, and one of those "fictitious" forces is the centrifugal force. If you're in a rotating frame of reference and want to accurately describe a particles trajectory, you must account for the centrifugal and Coriolis forces.

What are your thoughts on Dan Winter's theory of gravity being fractal charge collapse via golden ratio to implosion point at center ? (I know it's not mainstream, but math adds up if you look at his work) goldenmean dot info / gravitycause

[inphiknitfractal]

* non destructive charge collapse via golden ratio embed-ability....

yess just in time! thanks khan

Does the force of friction between the tire of the car and the road function in an analogous way as in the yo-yo example? ...My speculation here is that if the force of friction is parallel but opposite in direction to the velocity of the car, then the car will "want" to travel centripetally in consonance with the friction vector.

The thing I'd like to know is how does this change as the path becomes less circular and more elliptical. :o

u are awesome sir ... u understand the mentality of modern students and teach accordingly .... i totally like ur random style of teaching and ur sense of humour ... thanks a lot!!

[Shadowriku40]

I like the way he says "yo-yo." :D

I like the way he says "yo-yo." :D

physics! Thanks! I want more! And biology too!

[RTRVII]

ahhhh physics <3

[mdiem]

Nice. This was the next lesson I was going to do with my tutoring student. I like the focus on basic vector addition. Good review of some chapter one material.

A-Level physics flashback good times

Awesome! more physics vids :).
