Yes, when an object moves in a circular path, its velocity changes, and therefore there is acceleration. Here's why:

* Velocity is a vector: Velocity has both magnitude (speed) and direction.

* Changing direction means changing velocity: Even if an object maintains a constant speed while moving in a circle, its direction is constantly changing. Since velocity is a vector, a change in direction means a change in velocity.

* Acceleration is a change in velocity: Acceleration is defined as the rate of change of velocity. Since velocity changes in circular motion, there must be acceleration.

This acceleration is called centripetal acceleration and it always points towards the center of the circular path. It's what keeps the object moving in a circle instead of flying off in a straight line.
