Circluar Motion Flashcards
1
Q
Formula for angular speed
A
W=2π/T
2
Q
Formula for liner speed
A
V=wr
3
Q
Formula for frequency
A
w=2πf
4
Q
Formula for both liner and angular acceleration
A
A=V2/r and A= w2r
5
Q
Formula for orbital speed
A
G= V2/r
6
Q
Formula for centripetal force
A
F= mv2/r and F = mw2r
7
Q
What is centripetal acceleration?
A
It is the acceleration of the object towards the center of the circle when the object moves at constant speed around a circle
8
Q
Why doesn’t velocity increase if centripetal force increases ?
A
As centripetal force doesn’t have a component working in the direction of velocity it doesn’t affect velocity
