Question

state law of conservation oflinear momentum. derive if from newton 2 law of motion

Answer 1

Your Answer :

Law of conservation of linear momentum states that total momentum of the system is always conserved if no external force acts on an object or system of objects. ... Hence this equation implies that if no external force acts on the system of two colliding balls, the total momentum is conserved.

Answer 2

Newton's second law of motion says that rate of change of linear momentum of a body is equal to the net external force applied on it. If the net external force acting on a body is zero, then the rate of change of momentum is also zero, which means that there is no change in momentum.
