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?
