Determining 'g' on an incline lab

For todays class, we again went over the lab for the first maybe 10 minutes of class.  We then proceeded to finish it.  In this lab we place up to 5 books under the ramp and record it with the motion detector and LabQuest thing.  Yesterday we got up to 1 or 2 books and today was the rest, we calculated sine, and acceleration.  With the information we get from those we make a graph to get what the incline would be at sin90, or 1, which should equal to 9.8.  We used a new percent difference formula being the absolute value of accepted-experimental all over accepted multiplied by 100.  I guess that sums it up.

Next is Painter : )
