Question

State the law of conservation of momentum hence show that the linear momentum of the system Two bodies is conserved.

Answer 1

Answer:

in an isolated system mutual forces between pairs of particle in the system can cause Momentum change in individual particles but since the mutual forces for each pair are equal and opposite the momentum changes cancel in pairs and the total Momentum remains unchanged this fact is known as law of conservation of momentum.

the total momentum of an isolated system of interacting particles is conserved.

an important example of application of the law of conservation of momentum is a collision of two bodies.

consider two bodies A and B with initial Momentum P A and p b the bodies collide get a part with Final Momentum paid as a and PDS B respectively.
