okay so this is what i did to find the work done by overcoming friction: Ff = .9 N d = .91 m (Ff x d = Wf --> .9 x .91 = .82 J) hmm okay so how would you find the work done by friction using that calculation that you just said (change in total energy = work done by friction...
December 16, 2007

One way that I found was knowing the force overcoming friction (Ff). so the equation to fin dthe work would be Wf = Ff * d.. as you said above (force*distance). But what other calculation would you use to find the wasted work without knowing the friction force?

There are two ways to find how much work is done voercoming friction. One method entails knowing the force overcoming friction. What other calculation could be done to find this wasted work?
