5 True/False questions
thermal → Energy stored in chemical bonds.
elastic collision → Occurs when two objects collide and rebound so that the sum of their momentums and the sum of their kinetic energies are the same before and after the collision.
cooling → Loss of thermal energy.
partially elastic collision → One or both objects in a collision deform, some of the kinetic energy is converted to heat.
mass energy → The ability to do work.
