How do you do word problems involving "work" in them. Please, any help is appreciated.

I assume that you mean how do you calculate mechanical work.

 

If you apply a force to move an object then the work done will be the product of the force and the displacement of the object.

 

W=Fd (if F and d are in the same direction.

 

It can be more complicated if the force and displacement are in different directions, in which case:

W=Fd cos(theta) where theta is the angle between the force and the displacement.

  • 3 weeks later...

w = fd works if force is a constant

 

if force is variable, definite integrals would probably do the job
