the FORCE of FRICTON
A. I thought that the wide side on a block fo wood would be the side that would reaquier ( i know i spelled that wrong) the most force to pull because it has the most surface area but I found out that the side with the least surface ( the narrow side) took the most force to pull. What I learned about surface area, and weight of blocks I shall type in the next letters starting now. I learned that that if you have more weight on a smaller surface it will take more force to pull the block then if the block has the weight spread out and if you add more blocks the weight will add and it will be even more force needed to pull the block.
B.the scale measures the fricton force witch ( yes I spelled that wrong to ( I think)) is caused by pulling on the scale with gravity pulling the block down.
C.we would use almost no force to pull a block of wood across ice because it is very smooth so the force needed to pull the block will be about .1 newtons per block on the wide side of the block.
