Work = Force x Distance
0 0 0
if you push a box and it moves a distance in the direction towards you're pushing it.

- the work is done on the box because the object change displacement in the same direction as the force you applied.

then if you apply a force doesn't make the object move so no work is done.

calculating if the work is done

W = FD

f = force
d = displacement

another example.

if I push a chair with 10 N force along the 3 meters line. calculate if the work is done.


F= 10 newton
D = 3 meters

w = (10 Newton) (3 meters)
= 30 Nm or 30 J (equivalent to joules)
