Input work is always greater than output work.

Answer:
why -1000J is the greater work
Answer:
Explanation:
Yes, Input work is always greater than output work.
Reason behind the output work is always less than the input work:
The reason the output work is always less than the input work is because some of the input work is used to remove friction. Since efficiency is never 100%, it is always less than 100%. While every machine makes work easier, the amount of work done remains the same. Efficiency is the proportion of user-inputted work (input work) that the machine actually completes (output work). The reason the output work is always less than the input work is because some of the input work is used to remove friction.
A machine can only produce as much work as you put into it. To reduce friction, a machine's moving parts must employ a portion of the work input. The work output of a machine is never equal to the work input due to friction.
