Why is the work output of a machine always less than the work input?
In a real machine, the output work is always less because input energy will be converted to heat energy and lost.
What is meant by the input force and output force of a machine?
the input force is how much energy or force you put into the machine, the output force is how much energy the machine produces with the end product.
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.
Is it true that work output of a machine is always less than work input because of energy lost due to friction?
Yes this it true, because a percent of the input energy is converted to heat, which causes the output to became less than the input.
The of a machine is the ratio of its energy output to the energy input?

Why is the work output of a machine always less than the work input?
In a real machine, the output work is always less because input energy will be converted to heat energy and lost.
What is meant by efficiency of a machine?
It is the output energy compared to the input energy. This will always be less than 100%
Why in a real machine the output work is always less the input work?
In a real machine, part of the energy (or power) is always wasted.
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 the definition of output and input work?
Work Input- The work done on a machine as the input force acts through the input distance. Work Output - The work done by a machine as the output force acts through the output distance (What the machine does to the object (dependent on the force) to increase the output distance).
Is energy input usually greater than energy output?
The energy input is always greater than energy output.
What is meant by the input force and output force of a machine?
the input force is how much energy or force you put into the machine, the output force is how much energy the machine produces with the end product.
Why is work output by a machine always less than the work input?
It is usually unavoidable that some energy is wasted.
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.
Is it true that work output of a machine is always less than work input because of energy lost due to friction?
Yes this it true, because a percent of the input energy is converted to heat, which causes the output to became less than the input.

Does energy input always equals energy output?
Yes it does
