* Uniform Circular Motion: This means an object moves in a circle at a constant speed.
* Acceleration: Acceleration is the rate of change of velocity. Velocity has both magnitude (speed) and direction.
Why acceleration is not uniform:
* Changing Direction: Even though the speed is constant, the direction of the object's velocity is constantly changing as it moves in a circle. This change in direction means there is a change in velocity.
* Centripetal Acceleration: This change in velocity is caused by an acceleration called centripetal acceleration. Centripetal acceleration is always directed towards the center of the circle.
In summary: While the magnitude of the acceleration might be constant in uniform circular motion, its direction is constantly changing, making the acceleration itself non-uniform.
