when the Force and Dispalcement are in opposite directions, then the work done will be negative.
Explanation:
work is measure of change of energy.
according to work energy theorem, the net work done equals the change in kinetic energy. Work is a scalar quantity.
If the Force and Displacement both are in opposite direction , the angle between these two vectors would be 180 degrees.
we know w = F.S = F S cos Q
= FS cos 180
cos 180 degress = -1
so work done in this situation is negative
