A uniform circular motion is an accelerated motion. Explain it. State whether the acceleration is uniform or variable? Name the force responsible to cause this acceleration. What is the direction of force at any instant? Draw a diagram in support of your answer.

थोडक्यात उत्तर

उत्तर

When the object moves in a circular path with uniform speed, it means that its magnitude of velocity does not change, only its direction changes continuously. Hence, it is considered as uniformly accelerated motion.

In a uniform circular motion, the acceleration is variable.

An object in uniform circular motion experiences an inward net force. This force is called centripetal force.

The centripetal force is directed towards the center of the circular path.
