Question

In case of uniform circular motion which of the following physical quantity do not remain constant

Answer 1

In case of uniform circular motion velocity do not remains constant

Explanation:

• In circular motion particle moves along the circumference of the circle and it have two forces acting on it at every point of time these forces are centripetal force which keeps it to move in circle and another one is centrifugal force which keeps it to move away from the circle although centrifugal force is an imaginary force
• In circular motion velocity of the particle changes at every point of time because the direction of particle is different for different instants and velocity is a vector quantity hence with the change in direction it changes
• Direction of velocity of particle is always tangential at every point
