A roller coaster takes energy to make the first rise, but then it should be able to run the course of the track without any inpu
t of energy. This, however, is not true. Energy continues to be needed. This is because some of the energy is converted to sound energy, and some is given off as heat energy. This is a good example of which law? the first law of thermodynamics
the second law of thermodynamics
the third law of thermodynamics
the zeroth law of thermodynamics
