Ohai darr.

Okay so work is basically how far you move something.
Lets say that you were trying to move a refridgerator (Yay I can't spell refridgerator!) and you were pushing really really hard, but it didn't move after you pushed on it for like, 2 hours.
By scientific standards, you did no work. How do you cuculate work though?

Work is cucualted like this;
Force X Distance = Work.
In math, it looks like this;
Fd = W

So, when we were testing friction, my team got the fine sandpaper surface.
I had some trouble figuring it out, but my team had 2.25 friction force......(I think X3).... and then I multiplied by .1 and figured out that the amount of work my team did with 1 block over fine sandpaper is.......(*drumroll*)....

.225=http://
I love it when something like this happens!!!
and when we were doing the HOW MANY WASHERS, we figured out that 11 washers gave away about 4.1 newtons of power.
