Asian Posted February 6, 2007 Share Posted February 6, 2007 How do you do word problems involving "work" in them. Please, any help is appreciated. Link to comment Share on other sites More sharing options...
m4rc Posted February 6, 2007 Share Posted February 6, 2007 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.

alex Posted February 23, 2007 Share Posted February 23, 2007 w = fd works if force is a constant if force is variable, definite integrals would probably do the job Link to comment Share on other sites More sharing options...
