A body is moving with uniform velocity. Its______________________?
Correct answer: D. displacement from origin changes
- A. speed changes
- B. acceleration changes
- C. direction of motion changes
- D. displacement from origin changes
Explanation
Uniform velocity means both speed and direction remain constant, so the body continues changing its position and its displacement from the origin changes with time. Option d is correct; option c is wrong because a changing direction would mean the velocity was not uniform.

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.
