Question

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?

Answer 1

max

Step-by-step explanation:

in this case Chris said that the car stops which means that its energy has disappear we know that this is wrong because energy can't just disappear energy can't be destroyed and Sam told that energy can't be the towards so it should have become potential energy in order for a body to be up converted into potential energy we need to change its position in respect to gravity in this case is position is not change in respect to gravity where is Max is correct because due to the production of wastage energy each energy and sound energy is produced due to friction and that's what stop the car
