Question

Justify the statement that a uniform circular motion is an
accelerated motion.​

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.

Plzz mark me as brainliest

Answer 2

Question :

Justify the statement that a uniform circular motion is an  accelerated motion.​

Answer:

In a uniform circular motion , the speed of the body remains same but the direction of motion changes at every point. In uniform circular motion different velocity vector at different positions of particle. At each position the velocity vector v is perpendicular to radius radius vector r.

Hence velocity of body changes continuously due to continuous change in direction of motion of the body. As we know rate of change of velocity w.r.t. time is an acceleration.

Therefore , uniform circular motion is an  accelerated motion.​
