Distinguish between elastic and inelastic collisions.
Original Khojo Papers practice question — not from a past board paper.
Answer
In an elastic collision both momentum and kinetic energy are conserved, and the bodies separate after impact. In an inelastic collision momentum is conserved but kinetic energy is not, some of it being converted into heat, sound or deformation; in a perfectly inelastic collision the bodies move off together.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Collisions between molecules of an ideal gas are treated as perfectly elastic.
