∙ 14y agoWork output can never exceed work input because a machine can never do more work than you enable it to. Like, if work input was 1,000 then work output could never possibly be more than 1,000 (sorry, I forget the units used. )

The input work is always greater than the output work because when the machine is working some of the force is used to overcome the force of friction.

Is work output always equal to work input?
Yes the only thing a machine changes is force,distance or direction
Why is the output work always less than the input work for a real machine?
because output work is input work divided by two
When a machince is used to perform a task work output is always what than work input?
Work output is always less than work input. This is related to the Law of Conservation of Energy.
Why is work output always less than work input?
Work output is always less than work input because some work is lost to friction and heat which is created in the process of physics.
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 a comparison of a machine's work output and work input?
Output is always greater than input. The output is multiplied from input.
Is work output always equal to work input?
Yes the only thing a machine changes is force,distance or direction
What stronger work output or work input?
In theory, work output might be equal to work input; that would be 100% efficiency. In practice, the output of a machine will be less than the input; i.e., some energy will be lost.In theory, work output might be equal to work input; that would be 100% efficiency.

If a machine's input work and output work are equal it has a high what?
efficiency
How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent?
If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
Why is the work output of a machin never equal to the work input?
Some work input is used to overcome friction.
Why is work output always less than work input?
Work output is always less than work input because some work is lost to friction and heat which is created in the process of physics.
Why is always work output less than work input?
Work output is always less than work input because some work is lost to friction and heat which is created in the process of physics.

In order for work output to equal work input there must be?
Equalling for work input - now that's a fine idea
