Question

what is the angle between acceleration and velocity of a body executing uniform circular mention.​

Answer 1

Answer:

90 degree

Explanation:

when a particle is having a uniform circular motion, then it's angular velocity is constant along the circular path. But as its direction is changing so it will have a acceleration, acting towards the centre and this is called centripetal acceleration.

So, the direction of the centripetal acceleration is perpendicular to the velocity and towards the centre.
