Question

State an important characteristic of uniform circular motion. Name the force which brings about uniform circular motion.

Answer 1

In a uniform circular motion, the speed is constant throughout the motion, but yet it is an accelerated motion. Because the direction of motion of an object undergoing uniform circular motion changes continuously. Due to that, it has a variable velocity, which results in an accelerated motion. The force responsible for changing the direction of motion of the body in a uniform circular motion is known as the centripetal force.

So, we can say that the centripetal force is the force, which brings about the uniform circular motion.
