Question

state whether the acceleration is uniform or variable in uniform circular motion​

Answer 1

Answer:

acceleration is variable because the velocity keeps changing throughout the motion(the direction of velocity is tangential at every point during uniform circular motion)

Explanation:

pls mark me as the brainliest :)

Answer 2

Answer:

the acceleration is always constant in UCM

Explanation:

there are two types of acceleration present in the CM i.e. tangential and towards the centre.

as the tangential acceleration changes its direction but not magnitude thus it is zero while centripetal is constant
