Can velocity speed up an object?

Answer 1

Well velocity is basically the same thing as speed but with direction (velocity can be negative or positive and speed is always positive). l velocity l = speed

So a change in velocity means a change in speed.

Answer 2

Velocity is a vector quantity that includes speed and direction. It describes the rate at which an object's position changes. So, velocity can change the speed of an object by altering its magnitude or direction.
