Does a change in the speed of an object always produce a change in its velocity?

Does a change in the speed of an object always produce a change in its velocity?


Does a change in the velocity of an object always produce a change in its speed? Explain both.Does a change in the speed of an object always produce a change in its velocity?
Not necessarily. Speed could be constant and velocity change (by a change in direction of the moving object).





Not necessarily, either. A change in velocity of an object would bring about probably the same absolute magnitude of the velocity, which is the speed.Does a change in the speed of an object always produce a change in its velocity?
Speed refers to motion but not direction. Velocity is speed in a specified direction. So if the speed changes the velocity changes too, but velocity can change while speed remains the same. For example a thing moving in a circle has a constant speed but velocity is always changing.
Velocity is speed, but with a direction. So a change in speed will change velocity cause velocity is speed but with a direction
