Re: centripedal force

Yeah that's the formula, but I don't think there's a way to derive it.

Ok - obviously there is.

Re: centripedal force

Yeah, it does.

A = v²/r
Acceleration of circular movement of object = tangential velocity²/radius of circular object

F = ma
Force = mass.acceleration --> explained through Newton's 2nd Law of Motion I believe.

Since A = v²/r sub v²/r as a into f = ma
Therefore, F = m/1.(v²/r)
Multiply numerators and denominators seperately.
F = mv²/r

thanks man, you help me out a lot.

Fuck me. Not another thread. Learn to fucking google.
