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.
Explain why the amount of work that a machine does is less than the amount put into the machine?
Output work is always less than input work.
How is the efficiency of a compound machine calculated?
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.
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.
How can you increase the work output of a machine?
the only way to increase the work output is to increase the amount of work you put into the machine.

The amount of work done by a machine is called?
Its output.
What Is Color Output?
Output is not a color. It is the amount of something that is produced by a person, machine, or industry.
The of a machine is the ratio of its energy output to the energy input?
effeciency. study island
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.
Differences between input work and output work?
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.
What is the difference between a ideal machine and real machine?
In ideal machine input is equal to output . The efficiency of ideal machine is 100% . In real machine input is not equal to output .The efficiency of ideal machine in not 100% . In ideal machine there is no lose of energy . In real machine there is lose of energy . In real machine there is no friction . While in real machine there is friction .
What is the formula for efficiency of a machine?
useful energy output divided by total energy output x 100 give answer as a percentage, which is why you multiplied by 100
