Can a body have a constant speed and still have a varying velocity?

Can a body have a constant velocity and still have a varying speed ?

When a body moves with constant speed along a circle

If a body is moving in a circle of radius r with a constant speed v m/s. Its angular velocity is

A body whose speed is constant :

We have carefully distinguished between average speed and magnitude of average velocity. No such distinction is necessary when we consider instantaneous speed and magnitude of velocity The instantaneous speed is always equal to the magnitude of instantaneous velocity. Why?

Distinguish between average velocity and average speed. Is it possible that the average velocity of a body is zero, but its average speed is non-zero?

For a body moving along a straight line, the average velocity is equal to its instantaneous velocity. The motion of the body is

Obtain an expression for the centripetal force required to make a body of mass m moving with a constant speed v around a circular path of radius r.

How can we change the speed and the direction of a moving body?

Can a trapezium have all angles equal? Can it have all sides equal? Explain.
