Speed is a scalar quantity while velocity is a vector quantity.It is possible that an object can have constant speed but if speed is constant while direction of motion is changing constantly then it means that body has variable velocity.An example of this phenomena is a body moving in a circle whose speed is constant but velocity is changing every instant due to change in direction at every instant.

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 velocity and but variable speed?
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.
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.
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.
What is the condition in which a body moving with uniform speed has variable velocity?
Uniform circular motion. The speed is constant but the direction thus the velocity is variable.
Can a body have constant velocity but have variable speed explain?
No. Speed is the magnitude of velocity. If the speed varies, so will the velocity, even if you are moving in a uniform direction.
Can you go around a curve with constant velocity?
No. Constant velocity implies a constant speed, AND a constant direction.No. Constant velocity implies a constant speed, AND a constant direction.No. Constant velocity implies a constant speed, AND a constant direction.No. Constant velocity implies a constant speed, AND a constant direction.
If you have a constant velocity do you have to have a constant speed?
Yes, speed is the scalar of velocity.
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.
Is constant speed constant velocity?
No. Velocity includes a direction vector, which speed does not have.
Moving at constant velocity is also moving with constant speed?
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
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.
