Question

For an object moving along a straight line without changing its direction the(a) distance travelled > displacement
(b) distance travelled < displacement
(c) distance travelled = displacement
(d) distance is not zero but displacement is zero

Answer 1

Answer:

(c) distance travelled = displacement

Answer 2

For an object moving along a straight line without changing its direction, the (c) distance travelled = displacement.

Displacement is defined as the distance between the initial and final points of the object when we consider motion. On the other hand, distance refers to the actual physical movement of the object. Simply put, displacement is state dependent, while distance is path dependent. Since the object in the question is not changing direction, and moves in a straight line, the distance and displacement are equal.
