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 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 »

Temperature increases the reaction rate by increasing the number of collisions and making more forceful collisions. A rise in temperature is an increase of motion and energy, so collisions happen more often and more viol... More »

The momentum of a system is conserved in elastic collisions between system objects. The system must be isolated, indicating that it is free from the influence of a net, external altering force that affects collision proc... More »

According to Physics Classroom, elastic potential energy is a kind of energy kept in elastic materials due to compression or stretching by an external force. The elastic potential energy formula is P.E = 1/2 kx2. More »

Heat measures the movement of molecules in an object, while temperature measures the average energy or heat generated by the molecules in an object. The faster the molecules move, the more heat they produce and the highe... More »
