Here's why:
* Velocity is Tangential: In circular motion, the velocity of the object is always tangent to the circular path. This means the velocity vector is constantly changing direction, even if the speed is constant.
* Change in Velocity is Acceleration: Any change in velocity, whether in magnitude or direction, constitutes acceleration.
* Centripetal Acceleration: Since the velocity vector is constantly changing direction, the object is accelerating towards the center of the circle. This inward acceleration is called centripetal acceleration.
Key Points:
* Centripetal acceleration is not a separate force. It is the result of a net force acting on the object, directed towards the center of the circle.
* Without centripetal acceleration, the object would continue in a straight line (Newton's First Law).
