• When an object moves in a circle at a constant speed, it is said to undergo uniform circular motion.

• The time it takes the object to make one revolution is called the object's period P . If the object is moving at a constant speed, then

Centripetal Acceleration:

• In order for an object to execute circular motion - even at a constant speed - the object must be accelerating towards the center of rotation. This acceleration is called the centripetal or radial acceleration and has a magnitude of
