Motion in a circle at constant speed is motion with constant acceleration.

Question

Quizplus · Accepted Answer

Motion in a circle at constant speed is not motion with constant acceleration because the direction of the velocity is constantly changing, meaning there is an acceleration present. This type of acceleration is known as centripetal acceleration and its magnitude is given by a=v^2/r, where v is the speed of the object and r is the radius of the circle.
