Its output.
The work done by a machine is called work output
A force machine does not reduce the amount of work that has to be done
Machine work
yes
Work input is work done on a machine to get the desired output. Work output is the amount of desired work that is done by a machine.
work output
Because work is the amount of energy transferred into or out of a system, not counting energy transferred by heat conduction.
levverr
Yes, usually it will decrease it, since no machine is 100% efficient.Just in case you mean "the amount of work REQUIRED", then of course the machine will INCREASE that.
" power "
A watt is the amount of work per second.
The efficiency of a machine is found by dividing the amount of work done by a machine by the amount of energy used by a machine. The answer is then multiplied by 100 to give a percentage.
