Uniform Circular Motion
... increasing its speed or slowing down, there is also a non-zero tangential acceleration in the direction of motion. But when the object is moving at a constant speed in a circle then only the centripetal acceleration is non-zero. In all of these instances, when an object is constrained to move in a c ...
