Displacement should be in opposite direction of applied force

GarvAhuja: plz explain us
prakhar22221: means if you are providing fore in north direction then the displacement will be in south
prakhar22221: force
GarvAhuja: yes if we are providing a force in north direction then the displacement will be in south
prakhar22221: thats right
GarvAhuja: means frictional force is applying on it
prakhar22221: yes you can say force of friction
GarvAhuja: yes
prakhar22221: ok byee

The condition for negative work will be when force is applying opposite to the direction of displacement or you will say that when the cos o will be more than 90
We know that cos o more than 90 will always be negative
Therefore work will always negative
