Question

Solve the following:

(a) State the Law of Conservation of Momentum. Deduce it from Newton’s second

law of motion.

(b) Give reason for the following:

(i) An air filled balloon rise up slightly when punctured from below ?

(ii) A swimmer push water backward with his hands, in order to swim in forward

direction ?​

Answer 1

answer:-

Law of conservation of momentum. This law states that if a number of bodies are interacting with each other (i.e., exerting forces on each other), their total momentum remains conserved before and after the interaction, provided there is no external force acting on them. Derivation from Newton's second law of motion.
