Question

If the distance travelled by an object is zero, then the displacement of the object is

• A. zero
• B. not zero
• C. negative
• D. may or may not be zero

Answer 1

The correct option is A zero

Answer is A.
Distance can include linear or nonlinear measures between two points; displacement includes only a linear measure between two points.
For example,
If a person runs 100 m, both distance and displacement are 100 m.
If a person runs around a track once (400 m; assuming they are running in the first lane), the distance covered is 400 m but the displacement is 0 m.
Hence, If the distance traveled by an object is zero, then the displacement of the object is also zero.
