Question

can distance travelled by a body is zero?justify

Answer 1

Yes the distance travelled by a body can be zero if its final and initial position are at the same place.

Answer 2

suppose that when we throw a ball up in the air, for whole of the journey covered by the ball, displacement would be zero as the ball comes back to its original position in the final situation and hence the starting point and end point remains the same which means, shortest distance between terminal points is zero and displacement is zero
