You and two friends apply a force of 425 N to push a piano up a 2.0 M long ramp how much work in Joules has been done when you reach the top of the ramp?

If a force F (measured in newtons, N) is applied to move an object a distance d (measured in metres, m) in the direction of the line of force, the work done W (measured in joules, J) is given by:

W = F d

Crucially, d is the distance moved in the direction of the line of force. Assuming the force is applied parallel to the ramp:

W = 425 N x 2 m

= 850 J
