Question

State the conversation of linear momentum of an isolated system

Answer 1

Statement:

Law of conservation of momentum says that the linear momentum of an isolated system remains constant with the time.

Explanation:

An isolated system is a system whose mass remains constant and external force on that system is zero. Mathematically law of conservation of linear momentum can be written as  

                                     P1 = P2

                                 m1v1 = m2v2

Law of conservation of linear momentum is only applicable to closed system.
