Question

Is uniform circular motion an example of accelerated motion? Explain.

Answer 1

Uniform circular motion

1. When a particle moves in a circular path with a constant speed, the motion of that particle is called uniform circular motion.

2. In this motion the speed of the particle remains constant but the direction of motion changes continuously. So we can say that velocity changes in a uniform circular motion.

3. As the velocity of the particle changes, the particle must have acceleration. In the uniform circular motion, the acceleration acts along the radius of the circular path.

Thus, the answer is yes, a uniform circular motion is an example of accelerated motion.
