In this scenario a battery is used to supply chemical potential energy. The potential energy is transformed and produces kinetic energy. The battery causes a fan to spin and that kinetic energy can also be described as mechanical energy. Check out the values for each: 100 J potential energy results in 75 J of kinetic energy. What conclusion can be drawn from the energy transformation diagram?
