What is the formula to calculate useful work done?

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

Answer 2

work = (force) (distance)

To be totally correct, work is the dot product of the force and distance. Since force and distance are both vectors the angle between them is important. If force and distance is in the same direction then the formula

work=(force)(distance) is correct. Otherwise

work=(force)(distance)(cos(theta))

Answer 3

THE FORMULA IS W=FD W BEING WORK

F BEING FORCE D BEING DISTANCEHOPE THAT HELPED SOME

Answer 4

This is the general formula for work, without going into specifics:

Work = (Force)(Distance) (cosine of the angle between force and distance)= the change in kinetic energy

If you wan some specifics just holler.

Answer 5

The formula to calculate useful work done is given by:

Useful work done = Input work - Wasted work

Where Input work is the total work input to a system and Wasted work is the work lost due to inefficiencies in the system.

Answer 6

Work = Force x Distance; force is in newtons, distance is in meters

The unit for work is Nm (newton Meters)

Answer 7

To calculate useful work done, one could use an efficiency formula. Simply put, it is W= Fd. Work Done (J) = Force (N) x Distance (M) Work = Force x Displacement x cos.

Answer 8

Formula=work all ofar time taking

Answer 9

w=fd
