the same amount of work being done over a shorter period of time.
more work done over a shorter period of time.
more work done over the same amount of time.
the same amount of work being done over a longer period of time.
If we have less power, then we could have less work done in the same amount of time, or we could have the same amount of work being done over a longer period of time.
In either case, the quotient of work / time would be a smaller number.
