Question
What is the difference between ‘distance travelled’ by a body and its ‘displacement’$?$ Explain with the help of a diagram.

Answer

 
Distance
Displacement
$1.$
distance has only magnitude, with no specified direction.
Diplacement has magnitude as well as direction.
$2.$
It is a scalar quantity.
It is vector quantity.
$3.$
Two different distance can be added directly.
We have to follow the vector addition method to add displacements.
One difference in digramatic form is as follows:

Here the curved line is the distance traveled and the straight line is the magnitude of the displacement.

Akhtar, Kiran and Rahul were riding in a motorcar that was moving with a high velocity on an expressway when an insect hit the windshield and got stuck on the windscreen. Akhtar and Kiran started pondering over the situation. Kiran suggested that the insect suffered a greater change in momentum as compared to the change in momentum of the motorcar (because the change in the velocity of the insect was much more than that of the motorcar). Akhtar said that since the motorcar was moving with a larger velocity, it exerted a larger force on the insect. And as a result the insect died. Rahul while putting an entirely new explanation said that both the motorcar and the insect experienced the same force and a change in their momentum. Comment on these suggestions.
