Why is it impossible for the output work of a machine to be greater than the machine's input work?

There are always energy losses within the machine due to inertia, friction, etc.

Can you make work output of a machine greater then the work input?
No. And you cannot make it greater THAN the input, either.
Is it true or false that in some machines the output force is greater than the input force?
Output force CAN'T be absolutely greater than input force because energy is lost due to friction. However, the "mechanical advantage" of a simple machine can be greater than one because the machine applies the force over a different distance.
How input work and output work computed on each type of simple machines?
(Output work) + (friction losses) = (input work) on any type of machine.
Explain why the output work for any machine cant be greater than the input work?

If the output force is less than the input force of a simple machine the mechanical advantage is less than one.?
True ~ LiL' Diablo
A picture of a input and output machine in math?
if one answer is 6 and the other answer is 7, how do the output numbers from the input/output machines compare
What compares a machines work output with the work input?
That is called the machine's efficiency.
What compares a machines work output with work input?
That is called the machine's efficiency.
Is output force greater than the input force in some machines?
yes
What is a comparison of a machine's work output and work input?
Output is always greater than input. The output is multiplied from input.
What is a a comparison of a machines work output with the works input that is mechanical?
Output power divided by input power, for a machine, is called the machine's efficiency. It need not be mechanical energy.
Im most simple machines the work output of a machine will overcome the what?
Work input.
If a machine has a mechanical advantage much greater than 1 how will the output force be in comparison to the input force?
The Output Force Will Most Likely Be Greater Than The Input Force. So "OUTPUT" Is Greater Than "INPUT".

Why the output work for any machine cant be greater than the output explain?
-- The output work can't be greater than the output because they are, by definition of the terms, the self-same quantity, and consequently can be neither greater not lesser, but must at all times remain identical. -- The output work can't be greater than the INPUT ... unless additional energy is supplied inside the machine ... because total energy of a system is conserved, and cannot be created ex nihilo.
