Inelastic

Explanation:

If a football player running down the field is tackled by another football player who holds onto the first football player so that they both fly out of bounds together, that collision is inelastic.

An inelastic collision can be defined as a type of collision in which the total kinetic energy possessed by the colliding bodies doesn't remain the same as a result of internal friction.

This ultimately implies that, in an inelastic collision the maximum amount of kinetic energy possessed by the colliding bodies isn't conserved (kinetic energy is lost) after the collision, this is due to the action of an internal friction.

Mathematically, inelastic collision is given by the formula;

Where;

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
