What is the formula to calculating work?

Answer 1

W= Fd Work Done (J) = Force (N) x Distance (M)
Work = Force x Displacement x cos(θ) where θ is the angle between the direction of the Force and the direction of the displacement

As Force and displacement are both vectors and work is a scalar, the magnitude of the work is the scalar product of force and displacement

W = F.s

W = Fs cos(θ)
In order to simply determine work done on an object, figure out how much force was exerted on the object, and over what distance, and multiply them. If you are just pushing an object, figure out the force needed to overcome friction and how far it was pushed. The unit of work (and energy) most commonly used is the joule. It is one Newton of force applied over one meter. 2 joules could be one Newton pushed over 2 meters, or 2 Newtons pushed over 1 meter.
Work= force(N) x distance(M) or W=fd
