Answer 2

The scenario which best describes an object with a displacement of zero is D. A race car starts and ends at the same point on a track.

When can displacement be equal to zero?

When the endpoint and the first point of the object are the same then the displacement is called zero for example the circular object/body when you reach the first point after completing one complete circle is said to be non-removable.

What is an example of zero displacements?

When a car travels from A to B and then back from B to A. Distance = 10 +10 = 20 m. Displacement = Minimum distance between final(B) and initial position(B) = 0.
