Describe the factors that determine power in your own words (not from a website)

Since you put your question in the <Physics> category, I'll assume
you're talking about mechanical or electrical power, and not political
or military power etc.

Power is the rate of doing work or moving energy from one place
to another.

In mechanical contraptions, Work is (force) x (distance) ,
so
                           Power = (work) divided by (time)

                               or     = (force) x (distance) divided by (time).

In electrical circuits,

                           Power = (voltage) x (current)

                               or    =  (current)² x (resistance)

                               or    =  (voltage)² divided by (resistance) .

(Just use the formula with whatever quantities you know.)
