Answer 1

The best statement of the Law of Conservation of Energy from the options provided is:

**The amount of energy put out by a simple machine is always less than the amount of energy put into the machine.**

This statement reflects the idea that due to factors such as friction and inefficiency, not all the input energy is converted to output energy, which is consistent with the principle of conservation of energy. However, it's important to note that the total energy in a closed system remains conserved.
