Law of Conservation of Linear Momentum - 2 particles example
Description
In classical mechanics, linear momentum or translational momentum (pl. momenta; SI unit kg m/s, or equivalently, N s) is the product of the mass and velocity of an object.In a closed system (one that does not exchange any matter with the outside and is not acted on by outside forces) the total momentum is constant. This fact, known as the law of conservation of momentum, is implied by Newton’s laws of motion.Suppose, for example, that two particles interact. Because of the third law, the forces between them are equal and opposite.
