Question

When an object is in uniform circular motion, its ……… changes at every point. Complete the sentence and explain them.

Answer 1

Before discussing the dynamics of uniform circular motion, we must explore its kinematics. Because the direction of a particle moving in a circle changes at a constant rate, it must experience uniform acceleration. But in what direction is the particle accelerated? To find this direction, we need only look at the change in velocity over a short period of time:

Answer 2

Answer:

When a body is in uniform circular motion, its velocity changes at every point.

Explanation:

The circular motion is that kind of motion when moving body follows a circular path around a particular point.

We have two types of circular motion:-

• Uniform circular motion

• Non-uniform circular motion

Uniform circular motion:-

In the case of uniform circular motion where the motion of the body follows a circular path with constant or uniform speed.

• Velocity is vector quantity, it depends upon both magnitude as well as direction of body.

• In the uniform circular motion , the direction of body changes every point. Therefore, its velocity will change as well but the magnitude of the velocity remains constant. So, it is also called as uniformly accelerated motion.

• In the case of uniform circular motion, the angular speed  and acceleration remains constant, but the velocity of body changes.
• In non-uniform circular motion, both velocity and the angular speed change.
