Three students observe a toy car rolling across a level floor until it slows to a stop. After the observation, they make these statements: Max: "Energy is conserved, but friction turned it into heat, warming the floor and wheels." Chris: "But it stops. Energy is not conserved. The car's kinetic energy disappeared." Sam: "But energy can't just disappear. It must have become potential energy." Which student was correct?

In this case, The Max statement is correct because the energy is conserved and Total energy is equal to the sum of kinetic energy, potential energy, and energy which was against the friction between car wheel and the floor
