Question

The numerical ratio of displacement to distance for a moving object is
(a) always less than 1
(b) always equal to 1
(c) always more than 1
(d) equal to or less than 1

Answer 1

Displacement is the shortest distance traveled by an object. The magnitude of displacement can be less than or equal to the magnitude of distance, but it can never be more than that of distance.
Hence numerical ratio of displacement to distance for a moving object is equal to or less than 1.
