Answer 2

A man who has walked a certain distance but not in a straight line can have zero displacement.

Explanation:

• Distance is defined as the path covered by a body in a given interval of time.
• Distance is a scalar quantity which means it has only magnitude and is not dependent on the direction of motion of the body.
• Distance is the total path covered by the body inconsiderate of the directions that the body took.
• Displacement on the other hand is a vector quantity, it is the difference between the final position and initial positions of the body.
• Displacement depends on the direction of the body as it signifies the start and end positions of the body.

When there is change in direction of the body, then the distance and displacement of the body is different because the difference in initial and final points of the body will be different than the total path covered by the body.

If the body takes a straight path, distance will be equal to or same as the magnitude of displacement.
