Question

Give an example of the motion of a body moving with a constant speed, but with a variable velocity.Draw a diagram to represent such a motion.

Answer 1

A body in a uniform circular motion satisfies all your conditions.
A body in uniform circular motion has a constant speed, but the velocity varies as the direction of the velocity changes continuously. It has a centripetal acceleration acting on it whose magnitude remains constant but the direction which is radially inward, changes continuously its velocity,
