What happens if a body moves in a circle at a constant speed?

Circular motion is the movement of an object around the circumference of a circle or the rotation of an object along a circular path. A force acts continuously at right angles to the particle's velocity.

Uniform circular motion is defined as circular motion in which the particle's speed remains constant.

Force provides centripetal acceleration in a uniform circular motion.

Assume a body moves in a circular path at a constant speed. As a result, it will have centripetal force.

After one complete circle, the body's velocity returns to its initial direction.

Then, when a body moves in a circular path at a constant speed, its direction changes.

Thus, the body's velocity changes.
