Question

Velocity is a vector quantity. In how many ways can this vector be changed?

Answer 1

The velocity vector is constant in magnitude but changing in direction. But the fact is that an accelerating object is an object that is changing its velocity. And since velocity is a vector that has both magnitude and direction, a change in either the magnitude or the direction constitutes a change in the velocity.

There arethree ways an object can accelerate: a change in velocity, a change in direction, or a change in both velocity and direction.
