* Acceleration is a change in velocity. Velocity is a vector quantity, meaning it has both magnitude (speed) and direction.
* Circular motion involves constant change in direction. Even if an object is moving at a constant speed in a circle, its direction is always changing.
* This change in direction means a change in velocity. Therefore, the object is experiencing acceleration, even if its speed remains the same.
Imagine a car going around a roundabout. The car's speedometer might show a constant speed, but the car is constantly changing direction to stay in the circle. This change in direction is what constitutes acceleration.
The acceleration in circular motion is called centripetal acceleration. It's always directed towards the center of the circle and is responsible for keeping the object moving in a circular path.
