If you wanted to produce more power, what could you do to maximize power

In physics, power is defined as energy per unit time.  You will also hear it described as work per unit time.  The standard unit of measure for power is the watt, where a watt is defined as joules (energy) per second (time).  This is expressed as a fraction as J/s.  If you wanted to increase the power in any operation, you can either increase the energy (more joules) or reduce the time (fewer seconds).
