Question

Which of the given options represent the motion of an object that does not change its magnitude of velocity but only its direction of motion?

• A. Parachutist bailing out of an airplane.
• B. Uniform 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 Uniform motion of a body along a circular path

In uniform circular motion, the speed of the body remains same but its direction changes continuously. So, in a uniform motion along a circular path the magnitude of velocity remains same but the direction of motion changes.
