What is law of conservation of linear moment. Explain with one example.

Answer»

Conservation of momentumis a fundamental law of physics which states that themomentumof a system is constant if there are no external forces acting on the system.Newton's cradleis a device that demonstratesconservation of momentumand energy using a series of swinging spheres. When one sphere at the end is lifted and released, it strikes the stationary spheres, transmitting a force through the stationary spheres that pushes the last sphere upward.
