That is called the efficiency, and it is a number between 0 and 1 (or 0% and 100%). It is obtained by dividing output power / input power.

Is a measure of how much work put into a machine is changed to into useful work by the machine?
Efficiency
Why is a syringe more useful than a balloon to cunduct this experiment?
Because you can measure the amount of gas
A measure of how much work put into a machine is changed into useful work output?
It's efficiency would be 100%, but it's basically a theoretical ideal, because no matter how much it is minimized, "machine" automatically means a certain amount of friction, and a certain amount of heat generated, even if they are tiny amounts. That prevents 100% efficiency.
What is the world's useful machine?
What the most useful machine is, is a matter of opinion. Some would argue that the wheel is the most useful machine, and others would argue that the lever is the most useful.
How useful are machine?
A machine saves you force, changes distance, and changes direction. Those are the three ways in science that why machines are useful.
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.

When are newtons used to measure?
One newton (N) is equal to the amount of force needed to move 1 kilogram of substance one centimeter per second. This unit of measure can be useful when measuring the amount of force medium to large sized objects experience.
