Question

When a particle moves in a circle with a uniform speed it's volocity and acceleration both are constant.

Answer 1

Answer:

When a particle moves in a uniform circular motion, its speed as well as the centripetal acceleration is constant in magnitude but they continuously change their direction. Thus both the velocity and the acceleration changes in uniform circular motion.
