Which is the best statement of the Law of Conservation of Energy? (1 point) Responses The amount of energy put out by a simple machine depends on its efficiency. The amount of energy put out by a simple machine depends on its efficiency. The amount of energy put out by a simple machine must equal the amount of energy put into the machine. The amount of energy put out by a simple machine must equal the amount of energy put into the machine. The amount of energy put out by a simple machine is always less than the amount of energy put into the machine. The amount of energy put out by a simple machine is always less than the amount of energy put into the machine. The amount of energy put into a simple machine should be conserved.

The best statement of the Law of Conservation of Energy is: "The amount of energy put out by a simple machine must equal the amount of energy put into the machine."

is this correct

Yes, that is correct. The statement accurately captures the essence of the Law of Conservation of Energy, which states that energy cannot be created or destroyed, only converted from one form to another. In the case of a simple machine, the input energy must equal the output energy, in accordance with this law.
