If an object is moving in a circle at constant speed, then it is accelerating. True or false?

Asked by Breana1234

Answer (2)

True. Acceleration means any change in speed or direction of motion. In circular motion, the direction is always changing, so the motion is always accelerated, even at constant speed.

An object moving in a circle at constant speed is indeed accelerating because its direction is constantly changing, which constitutes a change in velocity. This type of acceleration is known as centripetal acceleration and is directed towards the center of the circle. Thus, the statement is True.
