An object is moving at constant speed, which of the following is always true?
Correct answer: A. Distance is greater than displacement
- A. Distance is greater than displacement
- B. Distance is lesser than displacement
- C. Distance is equal to displacement
- D. We cannot answer
Explanation
Distance can either be greater than displacement, or equal to it. However, even if both distance and displacement are not equal, distance is always going to be greater than displacement, therefore this situation is the one that prevails.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
