Question

Explain:
Why there is acceleration when there is a change in direction of an object ,which is moving in a straight line?​

Answer 1

Explanation:

The velocity vector is constant in magnitude but changing in direction. ... For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the velocity vector is changing.

Answer 2

Answer:

an object moving in uniform circular motion is moving in a circle with a uniform or constant speed. The velocity vector is constant in magnitude but changing in direction. ... It is accelerating because the direction of the velocity vector is changing.
