Question

Match the following
 

List - I List - II
a) Elastic collision e) e = 0
b) Inelastic collision f) 0 < e < 1
c) Explosion g) e = 1
d) Plastic collision h) Final K.E. > Initial K.E.

 

Easy
Solution

In explosion, chemical energy, stored in the explosive is released and appears as kinetic energy of the fragments 0 ≤ e ≤ 1. For perfectly inelastic collision, e = 0. For perfectly elastic collision e = 1
For partially inelastic collision 0<e<1
