* Acceleration is a change in velocity. Velocity includes both speed and direction.
* Circular motion involves a constant change in direction. Even if the speed is constant, the ball's direction is constantly changing as it moves in a circle.
The type of acceleration experienced by the ball in this scenario is called centripetal acceleration. This acceleration is always directed towards the center of the circle and is what keeps the ball moving in its circular path.
Think about it this way:
Imagine you're swinging a ball on a string. To keep the ball moving in a circle, you have to constantly pull on the string. This pull represents the force that causes the centripetal acceleration. Without this force, the ball would fly off in a straight line (due to inertia).
