I think they are one in the same. How much work can one do in as short a time as possible. That’s power: work (force x distance)/time. 200 pounds moved 2 feet in 3 seconds is more power than 200 pounds moved 2 feet in 5 seconds. The classic example of a power athlete is a 100 meter sprinter. Moving 200 lbs through 100 meters in less than 10 seconds is incredible power.
