Collision on A Linear Air Track Define momentum and kinetic energy momentum is a measure of the motion of a body equal to the product of its mass and velocity. Also called linear momentum . Kinetic energy is the energy of motion, observable as the movement of an object, particle, or set of particles. Any object in motion is using kinetic energy: a person walking, a thrown baseball, a crumb falling from a table, and a charged particle in an electric field are all examples of kinetic energy at work . Explain the conservation of linear momentum ? The law of conservation of linear momentum is a fundamental law of nature and it states that if no external force acts on a closed system of objects the momentum of the closed system remains constant . Explain the conservation of kinetic energy ? Satisfying conservation of kinetic energy means that the total kinetic energy before the collision is more than or equal the total kinetic energy after the collision since no energy can be created and energy could be lost to

An elastic collision is an interaction between objects in which both kinetic energy and momentum are conserved .. Define inelastic collision ? In an inelastic collision, the total momentum of the two bodies remains the same, but some of the initial kinetic energy is transformed into heat energy internal to the bodies, used up in deforming the bodies, or radiated away in some other fashion. Inelastic collisions, such as the collision of two balls of clay, tend to result in the slowing and sometimes the joining together of the colliding bodies . Define coefficient of restitution ? The constant e, which is the ratio of the relative velocity of two elastic spheres after direct impact to that before impact; e can vary from 0 to 1, with 1 equivalent to an elastic collision and 0 equivalent to a perfectly elastic collision ....
