Question

methods to produce a mechanical force output

Answer 1

Power is a physical concept that has several different meanings, depending on the context and the information that is available. Power can be a measurement of how much work someone or something performs over time. In a second context, power can be calculated as a function of velocity, how quickly you get a weight to move. Finally, electrical power is the product of voltage and current. If you know the context and you know which measurements you have to start with, you can select the appropriate formula and calculate power output.
