No. Velocity has two parts, speed and direction

A constant velocity means that both the speed and the direction must be constant. So a constant velocity must have a constant speed.

What is the difference between constant velocity and variable velocity?

Constant velocity has speed always constant along the direction with respect to time. Variable velocity changes its speed with respect to time. Constant velocity has zero acceleration. Variable velocity has non-zero acceleration . An object moving at a constant velocity maintains both the same speed and direction. An object moving at a variable velocity can be changing speed or direction of travel or both.


Can an object have constant speed but variable velocity?

I think a body in uniform circular motion can have a constant speed, but variable velocity. Since this body is in circular motion, it changes it's direction. Thus having a variable velocity.


When can an object a constant speed but not a constant velocity?

Consider an object turning in a circle at a constant speed. Because velocity is not just the value of speed, but also the direction in which the object is moving, the velocity would not be constant.


What happens to the velocity of an object even if the speed of an object remains constant?

Velocity can change even if speed is constant.


Can an object have a constant speed and velocity at the same time?

Yes. An object moving in a straight line at constant speed has constant velocity.


Can a body have a constant velocity but a varying speed?

No. Velocity is speed and direction. If you change either variable, the velocity will no longer be constant.


For an object to be moving at a constant velocity is it necessary for it to be moving in a straight line?

Velocity is a vector quantity in which both magnitude and direction must be taken into consideration. For an object to have constant velocity, it is necessary that both the magnitude and the direction of the velocity must be constant. Even if either magnitude or direction is variable, velocity will not remain constant. On the other hand, speed remains constant if direction is changed and magnitude is kept constant, as speed is a scalar quantity.For an object to have constant velocity, it is necessary that the object move at a constant speed and not change course. That object must move in a straight line to have a constant velocity.


Can an object have a varying speed it its velocity is constant?

No. Speed is the magnitude of the velocity. If either or both the speed and direction vary, the velocity is not constant.


Can the speed of an object changes if there is constant velocity?

No, constant velocity implies constant speed. But velocity can change even when speed remains constant, since speed is a scalar quantity but velocity is a vector quantity.


Can an object have a varying speed if its velocity is constant?

No, velocity is a vector quantity and measures both speed and direction. If the velocity of an object is constant then that would also mean the speed would stay constant.


Can an object have a varyong speed if its velocity is constant?
