The definition to energy input is something in a system or expended in its operation to achieve output or a result.
That means that there is something called energy that can't be created nor destroyed. The total amount of energy in a closed system remains constant.
When heat is added to or is absorbed by a system, its internal energy increases. The amount of external work a system can do essentially refers to the amount of energy it can transfer to something else. So when internal energy increases, so does the external work done by the system.
It helps to think of work as "transfer of energy". If you do energy on a system, its energy content increases. If the system does work on something else, the system's energy content decreases.
The total kinetic energy within a system
It is when something releases its energy to its surroundings do to a system.

A closed system is defined as a something that is isolated from its surroundings by a boundary that admits no transfer of energy or matter. It is an isolated system with no interaction with its external environment.
Well without the digestive system you won't have the energy to lift something up.
i would tell every body to save energyor to dont turn on something if your not using it
Energy is the potential to do some work. If there is work done on a system, this work done is stored as potential energy of the system. If the system in motion, it should have kinetic energy. Hence total energy of the system PE+KE
There is at least one non spontaneous reactions occuring in the particular system. So someone or something has to shred energy in order to continue the procedure.
