The formula for an elastic collision for the conservation of momentum is m1v1 + m2v2 = m1v1 + m2v2. The formula for the conservation of kinetic energy in an elastic collision is 1/2 m1v1^2 + 1/2 m2v2^2 = 1/2 m1v1^2 + 1/2... More »

The collision between two gas molecules or billiard balls can be approximated as elastic collisions. Elastic collisions are exchanges of kinetic energy between two bodies having different reference frames in which the to... More »

A perfectly elastic collision is a collision between objects during which there is no loss of kinetic energy and energy is fully conserved. No energy is dissipated as heat energy internal to the objects, and no energy is... More »

The law of conservation of momentum can be stated as, "When two separate objects collide with each other in an isolated system, the total amount of momentum of the two objects prior to and after the collision would remai... More »

Earth spins on its axis due to the conservation of angular momentum. When two objects collide, unless they hit exactly head on, spin will be introduced to the system. More »

The Earth spins on its axis due to angular momentum conservation. The Earth was formed when leftover gas from the sun condensed into planets. As the gas cooled, it condensed, which caused the Earth to start spinning. Bec... More »

The law of conservation of momentum says that the momentum before an event must be the same as the amount after due to its constant conservation. It is an element of the law of inertia. More »
