This document discusses linear momentum and collisions. It explains that impulse and momentum relate to object collisions like vehicular accidents. The total momentum before and after a collision must be equal according to the law of conservation of momentum. An inelastic collision is one where kinetic energy is lost, though momentum of the system is still conserved.

22. • An inelastic collision is a
collision in which there is a loss
of kinetic energy.
• While momentum of the system
is conserved in an inelastic
collision, kinetic energy is not.
