Question

Why uniform circular motion is called an accelerating motion? Explain.​

Answer 1

Answer:

One such case is uniform circular motion where the direction of velocity varies smoothly as we move about the circle. Despite the constancy of speed, the direction of motion is changing and therefore the time rate of change of velocity is nonzero—which constitutes an acceleration.

Explanation:

Answer 2

uniform circular motion has speed constantwu throughout, but its velocity gets changed and changing velocity is called acceleration.

Explanation:

in uniform circular motion, at ever point tangent to the given circular path is different, which implies that direction of velocity keeps getting changed at each point resulting in accelerated motion. remember that speed has only magnitude and no direction and velocity is a vector, having both magnitude and direction. its direction is given by tangent at any point. sand acceleration, a vector , is defined on velocity and not on speed.

i hope this answer helps:)
