POSITIVE WORK

When the force and the displacement are in the same direction then there will be positive work.

NEGATIVE WORK

When the foce and the displacement are in the different direction then there will be negative work

ZERO WORK

When there will be no displacement then the work will be zero means

W =F×S
W=F×0
W=O
