Question

*assertion*:uniform circular motion is also called accelerated motion..


*Reason*:Direction of motion changes at every point so velocity is not constant..​

Answer 1

Answer:

Uniform circular motion is accelerated because the velocity changes due to continuous change in the direction of motion. So, even when the body moves ta a constant speed, its velocity is not constant. ... Therefore circular motion is an acceleration motion even when the speed remains constant.

Explanation:

Answer 2

Assertion and reason both are true and the reason is the correct explanation for assertion.

Explanation:

Acceleration is defined as the rate of change in velocity with respect to time.

• Velocity is a vector quantity and has two components: magnitude and direction.

• Even if there is any change in direction of the velocity, the acceleration comes into play.

• In a circular motion, there is a constant change of direction of motion, which results in a change in direction of velocity as there is no straight path, the path followed by the body is circular.

• This change in velocity gives rise to acceleration.

• So, a uniform circular motion may be constant magnitude of velocity but there is still change in direction.

Therefore, a uniform circular motion is an accelerated motion
