When an object moves in a circular path, --------------.
Correct answer: D. Its displacement is always zero
- A. Its displacement is constant
- B. Its displacement changes due to change in distance
- C. Its displacement changes due to change in direction of motion
- D. Its displacement is always zero
Explanation
At the end of each revolution, the object returns to the initial point. Therefore, the net displacement covered is zero. Therefore, D is the correct option.

About Displacement and Velocity
Displacement is the directed change in position, while velocity is the rate of change of displacement and includes both magnitude and direction. The topic connects position-time and velocity-time graphs with average and instantaneous values, and distinguishes displacement from distance and velocity from speed.
