Answer:
the rate of change of angular position of a rotating body.
Centripetal Force
Because an object in uniform circular motion undergoes constant acceleration (by changing direction), we know from Newton's second law of motion that there must be a constant net external force acting on the object. ... Therefore, the magnitude of centripetal force, Fc, is .
