Question

In case of a moving body displacement is less than and equal to the distance . explain why?

Answer 1

Displacement is the shortest distance b/w final and initial point and distance is the actual path covered by moving body.
When a body moves in a straight line then their distance and displacement would be same.If body moves in another trajectory (straight line path) then displacement would be less than actual distance for eg a body moves in circle ,after completing one circle then its actual path covered(distance) would be 2πr and shortest distance b/w initial and final point (displacement) would be zero.

Answer 2

Because displacement is a vector quantity.so while traveling,path can be zig zag shapes So distance is always equal or greater than displacement.
