Question

The distance and displacement between two points for a moving body will be the same when ___

• A. distance and displacement are of equal magnitude.
• B. the body travels without changing its direction towards the final point.
• C. the body's initial point and final point are the same.
• D. a body is moving in a circular path.

Answer 1

Answer: (A), (B)

The correct options are
A

distance and displacement are of equal magnitude.

B

the body travels without changing its direction towards the final point.

The distance and displacement of a moving body will be the same only when both their magnitudes are the same and the body is traveling in the same direction. Every time a body changes its direction, the distance traveled will be more than the displacement.

Therefore, either of the cases can be true for distance and displacement to be equal.
