Question

Which of the following option is incorrect?

• A. Displacement can be equal to distance.
• B. Displacement is the shortest path between two points.
• C. Displacement can never be greater than distance.
• D. Zero displacement always means that the body is at rest.

Answer 1

The correct option is D Zero displacement always means that the body is at rest.

Displacement is the shortest distance between the initial and the final positions. Distance is the total path length travelled by the object. Therefore it can never be zero or negative. Hence, displacement can never be greater than the distance.

Zero displacement only means that the initial position and the final position coincides. It does not mean that the body is at rest.
