Look at the figure below and answer the following questions: Name the force that keeps the stone in its path.

Centripetal force keeps the stone in its path. The stone is moving with circular motion. Circular motion is the kind of motion in which the body travels in a circular path. If the body is undergoing uniform circular motion, then it will be an accelerated motion.

Look at the figure below and answer the following questions: Is this an example of accelerated motion? Why?

The stone is moving with circular motion. Circular motion is the kind of motion in which the body travels in a circular path. If the body is undergoing uniform circular motion, then it will be an accelerated motion.
