Question

What is law of conservation of momentum

Answer 1

conservation of momentum. A conservation law stating that the total linear momentum of a closed system remains constant through time, regardless of other possible changes within the system.
Newton's cradle is an example of the Law of Conservation of Momentum. noun. Law of conservation of momentum is defined as a principle in physics that says that some parts in an isolated system remaining steady and unchanging over time even when others are moving.

Answer 2

According to the law of conservation of momentum : When two ( or more) bodies act upon one another, their total momentum gain remain constant ( or conserve) provided no external forces are acting., simply Momentum is never created nor destroyed but only transfer from one body to another
