Answer 1

Answer:

The motion of a body in a circular path with uniform speed has a variable velocity because in the circular path, the direction of motion of the body continuously changes with time.

Answer 2

Only in case of uniform circular motion, this happens.

Explanation:-

• Speed is a physical quantity only specifying magnitude. Or, it is a scalar quantity.
• But, velocity is speed which describes direction.
• In case of uniform circular motion, a body changes it's direction, but it's magnitude remains same.
• Thus, it has a constant speed and variable velocity.
