On Monday November 3, 2008 Mr. Manning began class by passing back our recently taken tests and our reading guides for the past unit. At this point, Mr. Manning reviewed the test and asked if there were any questions. He then answered any questions the class had and discussed that any late work we had must be turned in before the end of the marking period if we wished for it tocount for credit and not be counted as a zero. Next he explained the next lab we would be doing, the //Force and Motion Lab.// When he was done with this we broke into lab groups of three people each and began work. We had to set up a moving force scale and a motion detector on a track. The motion sensor was hooked up to the computer and both the force scale and motion sensor were zeroed out. We then placed a 1000g weight on the force scale and then a 50g weight on a string at the end of the force scale. The weight on the string created a foece that pulled the force scale on it's sled along the track, which was then graph on the computer by the motion detector. The lab will be continued tomorrow.
