* Acceleration is a change in velocity. Velocity is a vector, meaning it has both magnitude (speed) and direction.
* The ball's direction is constantly changing. As the ball travels in a circle, its direction is always changing, even if its speed remains constant.
* This change in direction means a change in velocity, which means acceleration.
Think of it this way:
* If the ball were moving in a straight line at a constant speed, it would not be accelerating.
* But because it's moving in a circle, it's constantly being pulled towards the center of the circle. This inward force is what causes the ball to change direction and therefore accelerate.
This type of acceleration is called centripetal acceleration. It's always directed towards the center of the circular path.
