Since acceleration represents the rate of chage of velocity, how is it possible

Question

Since acceleration represents the rate of chage of velocity, how is it possible for an object moving in a circle to be accelerating if its speed never changes? Because acceleration is defined differently (in terms of vectors) in the case of circular motion Because the speed alternates between positive and negative as the object moves around the circle Because the direction of the velocity is changing, even if its magnitude is not Because each of the components of velocity are changing, even though the total velocity is not Submit

Explanation / Answer

Option (c) is correct.

Because the direction of the velocity is changing ,even if it's magnitude is not. Because velocity vector change in it's direction in all time . So tangential acceleration may be zero or constant but radial acceleration must be there.due to change in velocity.
