When an object is moving at constant speed, which of the following is always true?
Correct answer: D. There is not enough information available
- A. Distance is greater than displacement
- B. Distance is less than displacement
- C. Distance is equal to displacement
- D. There is not enough information available
Explanation
We cannot determine the relationship between distance and displacement by using information about speed. Hence, there is not sufficient information available, and option 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.
