Conditions of Use 1. 6.1 I learned that theres more friction if
you pull the block across fine sandpaper rather than coarse
sandpaper. 6.2 I learned that coarse sandpaper does go up steady
with 2 or 3 blocks. 6.3 I learned that there is more friction
when theres more wieght in one spot. 2. We measured by taking a
spring scale hooking it up to the block and pulling it 27
cent.Then we measure what the spring scale reads and we do three
trials and then get the average.This is measuring friction
force. 3. We kept the surface Type the same because if we
changed two variables we would have innacurate data. Article
