At the beginning of class those of us who originally did yesterday's lab on the relationship between mass and friction had to convert mass to normal force. We then whiteboarded our results and discussed them. Paulina and I, being the brilliant people we are, somehow measured the mass of the block to be 124 kg, so I spent a lot of the discussion trying to figure that little mess out. However, what I did get out of the conversation was that we explained the relationship between the normal force and the frictional force using the following equation:
Ff=uFn
(u=coefficient of friction)
Now for the second part of class. We did another lab slightly resembling yesterday's, except today we used the more rough side of the board, and we found the force when the block was stationary (as much force as it had right before it began to move) as well as the force as it was moving at a constant speed. We should be comparing our results tomorrow.
