Research / Linear Momentum

Momentum, also linear momentum, in physics, fundamental quantity describing the motion of any object. Momentum is a vector quantity, meaning that it has both amount and direction, and it is the product of the mass times linear velocity of a moving object. For an isolated system, total momentum remains unchanged over time. This conservation of momentum is one of the most important and universal of the conservation laws of physics. It holds true even when relativity must be used for systems moving with velocities that approach the speed of light, and even when quantum theory is used to describe atomic and nuclear events and forces. According to Newton's second law of motion—named after English scientist Sir Isaac Newton—a force acting on an object in motion is equal to the rate of change of momentum over time.

• Momentum - The momentum of a particle is defined as the product of its mass times its velocity. It is a vector quantity. The momentum of a system is the vector sum of the momenta of the objects which make up the system. If the system is an isolated system, then the momentum of the system is a constant of the motion and subject to the principle of conservation of momentum.
