A lab report of an object in freefall and the effects of gravity.

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. …showed first 75 words of 1070 total…

…showed last 75 words of 1070 total…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.
