Let me explain this one for you....
Work is a scalar quantity.
Here + or - sign indicates gain or loss of work respectively.
It is not indicating direction.
Forces appear always in pairs.
If for one force there is a gain of work, there will be an equal loss for the other force.
Simply , if there is a gain , there will be an equal loss.
Hence one can speak of minimum loss or minimum gain.
In both cases, zero is the minimum loss and minimum gain.
No gain , then no loss and vice versa.
When work is negative, there is loss. Loss will be minimum for zero value.
When force is perpendicular to displacement, no work is done. No gain or no loss.
Hope it helps
