Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle. ... The direction of the acceleration is inwards.

Which is correct for uniform circular motion?

answer : option (D) the direction of acceleration is changing. for uniform circular motion, speed of particle remains constant. i.e., magnitude of velocity remains constant.

WHAT IS A in uniform circular motion?

Uniform circular motion, motion of a particle moving at a constant speed on a circle. In the Figure, the velocity vector v of the particle is constant in magnitude, but it changes in direction by an amount Δv while the particle moves from position B to position C, and the radius R of the circle sweeps out the angle ΔΘ.
