 KOBY We have three 6th grade Science classes and two 8th grade Science classes blogging here from the Pacific Northwest in Chimacum, WA! Sixth graders are learning a bit about Mt Saint Helens, environmental science through fresh water ecology, and physical science this year. Eighth graders are learning about life science this year. Please join us as we learn Science by exploring our world. Mr. G's Blog Mr. G's Class Facebook Page

Work 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.
