P = W / t, in watts.
Two engines can do the exact same total work, but the one that does it faster has more power — power measures the rate of energy transfer, not the total amount transferred.
A watt is one joule per second — light bulb wattage, car horsepower (746 watts each), and your electricity bill's kilowatt-hours all trace back to this same rate-of-energy concept.

Power (W): 50
Delivering 500J of work over 10s is 50 watts of power.
