Answer:
The answer is time
Step-by-step explanation:
So when youre given force and distance, you can determine work done
Work Done = Force × Distance travelled in the
direction of the force
Since Power = Work Done/ Time
when you know work done, and you want to find power, you will need time.
Because you have work done already, you dont need energy. Though you can use energy and time to find work too. The alternative formula for Power would be:
Power = Energy Converted/Time
