Question

Is uniform circular motion of an object accelerated or not ? Give reason .

Answer 1

Answer:

yes, it is accelerated motion

Explanation:

• in uniform circular motion,speed is constant. but, velocity changes, because,velocity is a vector quantity and in circular motion direction changes continuously.

(velocity at an instant is represented by drawing a tangent to the curve...)

• As, there is a change in velocity, there will be an acceleration too..(which is known as centripetal acceleration)

Answer 2

Question :-

Is uniform circular motion of an object accelerated or not? Give reason.

Answer :-

Accelerated motion takes place when an object changes its speed or direction. Uniform circular motion is accelerated because in the circular motion there is a continuous change in direction of motion that leads to change in the velocity. Therefore circular motion is an acceleration motion as the direction is changing even the speed remains constant.

For example: The second, minute, and hour hands of a watch.
