Which quantities are conserved in an elastic collision?

Hints
  1. Elastic means nothing is lost to deformation or heat.
  2. Individual velocities certainly change, only totals can be conserved.
Show the answer
  • A. Total mechanical energy
  • B. Total kinetic energy
  • C. Total momentum
Why

Elastic collisions conserve both momentum and kinetic energy.
