Answer 2

$<h3>Law of Conservation of Momentum </h3>$

This law states that when no external force acta on a system of several interacting particles, the total linear momentum of the system is conserved. The total linear momentum is the vector sum of the linear momenta of all the particles of the system.

Two examples of illustrating law of conservation of momentum :

$<h3>1 ). Recoil of gun. </h3>$

$<h3>2. Rocket and jet work on this principle. </h3>$

$<h3>Explosion of a bomb. </h3>$
