Introduction
Uniform circular motion refers to the motion of an object moving along a circular path at a constant speed. In this type of motion, the object experiences a continuous change in direction, even though its speed remains constant. The question arises whether this motion is accelerated or not.
Understanding Acceleration
Acceleration is defined as the rate of change of velocity. Velocity is a vector quantity that includes both speed and direction. If an object changes its speed, direction, or both, then it is said to be accelerating.
Acceleration in Uniform Circular Motion
In the case of uniform circular motion, the velocity of the object is constantly changing due to the change in direction. Therefore, the object is always accelerating, despite moving at a constant speed.
Centripetal Acceleration
The acceleration experienced by an object moving in a circular path is called centripetal acceleration. It is directed towards the center of the circle and is always perpendicular to the velocity vector at any point on the circle. Centripetal acceleration is responsible for keeping the object on its circular path.
Centripetal Force
According to Newton's second law of motion, a force is required to cause an acceleration. In the case of uniform circular motion, the force responsible for the centripetal acceleration is called the centripetal force.
Key Points:
- Uniform circular motion involves an object moving along a circular path at a constant speed.
- Acceleration is defined as the rate of change of velocity.
- In uniform circular motion, the object's velocity is constantly changing due to the change in direction.
- The acceleration experienced in uniform circular motion is called centripetal acceleration, which is directed towards the center of the circle.
- Centripetal acceleration is responsible for keeping the object on its circular path.
- According to Newton's second law of motion, a force is required to cause acceleration, and in uniform circular motion, this force is known as the centripetal force.
Conclusion
In conclusion, uniform circular motion is indeed accelerated because the object constantly changes its direction, resulting in a changing velocity. The centripetal acceleration and the corresponding centripetal force are responsible for maintaining the object's circular path.

Yes the above statement is true because in the circular path there is always a change of direction in its paths. And we know that if velocity changes means if direction changes then there is always an acceleration.
