Question

Which of the following example shows, an object does not change its magnitude of velocity but only its direction of motion ?

• A. Parachutist bailing out of aeroplane
• B. Motion of a body along a circular path
• C. A body moving up against gravity
• D. A car moving with uniform velocity in a straight line

Answer 1

The correct option is B Motion of a body along a circular path

In circular motion, the body moves in reference with a fixed point with a fixed radius hence, its magnitude remains constant. Since the body is moving circularly, its direction also changes. So, motion of a body along a circular path has constant velocity and different direction.
