Explain the principle of inelastic collision

The kinetic energy lost in the collision appears in the form of heat energy, sound energy or light energy. The forces of interaction in an inelastic collision are non-conservative in nature.

Most of the collisions between macroscopic bodies are inelastic collisions. If a ball is dropped from a certain height and it is unable to rise to its original height, it would mean that ball has lost some kinetic energy (which would appear as heat energy). This would mean that collision is an Inelastic Collision.

Collision is a free event which takes place between the two or more than molecules. This is completed within a short time period. The concept of collision is based on the conservation of momentum and change in the kinetic energy. These laws imply that there is no change in the total momentum and kinetic energy of the system when the collision takes places. It is classified in two types,ƒ€š‚

Elastic collisionInelastic collision.The elastic collision involves conservation of momentum and kinetic energy without dissipative force. The collision between hard steel balls or swinging balls, ideal gases collision and also the collision of atomic or nuclear scattering is elastic in nature. The inelastic collision is the collision which involves only change in kinetic energy. All ordinary collisions are inelastic in nature because in this collision, the kinetic energy is changed into internal energy; for examples, collision between car, trucks or airlines etc.

Here, we are discussing about inelastic collision in one dimension and two dimensions, a perfect collision, and its mathematical formulation.
