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.

Can an object have constant velocity and but variable speed?
No, an object cannot have constant velocity and variable speed. Velocity is a vector quantity that includes both speed and direction. If the object's velocity is constant, then its speed must also be constant.
What is the difference between constant velocity and variable velocity?
Constant velocity means that an object is moving at a steady speed in a straight line, without changing its velocity. Variable velocity means that an object's speed or direction is changing over time, resulting in a non-constant velocity.
Can a body have constant speed as well as variable velocity?
No, constant speed implies that the body is moving at a consistent rate, while variable velocity means the direction of motion is changing. It is not possible for a body to have both constant speed and variable velocity simultaneously.
What is the condition in which a body moving with uniform speed has a variable velocity?
The condition in which a body moving with uniform speed has a variable velocity is when the direction of motion changes even though the speed remains constant. This means that the object is accelerating, even though its speed does not change.
What is the difference between uniform and variable velocity?
Uniform velocity is constant speed in a straight line, while variable velocity changes in speed or direction over time. Uniform velocity has no acceleration, whereas variable velocity may have acceleration due to changes in speed or direction.
