Question

When does the velocity change?

Answer 1

Hii,

A change in speed, or a change in direction, or a change in both speed and direction means that the object has a change in velocity. Understand that in physics this means if you turn a corner, even if your speed is constant, your velocity changes. Often thevelocity of an object is not constant

Hope this answer helps to you☺️✌️✌️

Answer 2

Hii there!!!

The rate of change of displacement with respect to time is called velocity.

The velocity changes when there is change in displacement.
