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