Purpose: The purpose of this lab is to prove that the acceleration of gravity is 9.8m/s/s. We did this by taking a time lapse photo of a ball dropped with a meter stick next to it. While the ball was dropped, a strobe light was flashing 3000 times per second, which created measurable points of the balls descent. Then we did a few different graphs of the data points by hand and computer. Procedure: 1. …

…a suspended meter stick. When you drop the ball parallel to the meter stick with the strobe light on and the cameras shutter open, you get a picture of the ball every flash of the strobe light. This results in about 16 data points along a meter stick. Another lab technique learned in this lab is using computer-graphing software, which results in a much lower percent error due to computers being more accurate than humans are.
