scientifically, what is input energy and what is output energy?

Answer 1

Input energy is the energy that is put into a system or process in order to make it work. This can be in the form of electricity, fuel, or any other source of energy that is used to start or sustain a process.

Output energy, on the other hand, is the energy that is produced by the system or process as a result of the input energy. This can be in the form of heat, light, motion, or any other form of energy that is generated as a result of the input energy being converted or transformed within the system.
