Q
Angular speed formula
A
Angle swept over time taken
2
Q
Relation between linear speed v and angular speed w
A
v = rw
3
Q
Centripetal acceleration formula and direction
A
a = v^2/r towards the center of the circle
4
Q
Centripetal force two formulas
A
F = (mv^2)/r
F = mw^2r
w = angular velocity
5
Q
Why doesn’t centripetal force do any work?
A
The force is at right angles to the direction of motion
