Centripetal Acceleration and Centripetal Force
... Circular Motion • When an object moves in a circle at constant speed, we describe it as undergoing uniform circular motion. • Its speed is constant, but its velocity is not because velocity includes direction and the object’s direction is clearly changing. ...
