Introduction Laboratory experiment three focused on Newton’s laws of motion. During part one, our group investigated Newton’s first law of motion which emphasizes that an object in motion will stay in motion unless acted on by an outside force. In our experiment, we observed the movement of a cart on a low friction surface and questioned if the object would stop moving without a force pushing it. Part two of the lab lead our attention to Newton’s second law of motion, which supports the concept that force is equal to mass multiplied by acceleration. During part two, we looked to see if this concept was reflected in our cart’s velocity while varying hanging masses pulled in down the low friction track. The full account of our laboratory experiment is as follows Part one procedure: Though our experiment was set up prior to our group arriving to lab, our first step in conducting our experiment was to inspect the instruments used and make adjustments where needed to make our data both more accurate and precise. These adjustments included leveling the low friction track (ID#...) until the cart would no longer roll either way when placed on it. We also adjusted the CBR (Computer Based Ranger ID#...) so that it accurately read the varying distance of the cart on the track. Lastly the CBR was plugged into a TI-84 calculator and test trials of operating the program were completed to insure we were correctly using the software.
