Preamble
After recently finishing up a take home test on the topics of energy conservation we were given an energy conservation lab for a deeper and more intricate analysis of the law of the conservation of energy. As previously mentioned by many physicists the law of conservation of energy states that energy cannot be created or destroyed, but it can be transferred or transformed from one form to another. Also the total amount of energy in a closed system never changes. Along with my wonderful partner Kelvin we thought that energy in a closed system will remain constant throughout unless there is an outside energy such as “work” or friction. We also discussed the differences and similarities between closed and open systems. We wanted to test this theory with the lab provided to us.
Materials
Before we start any lab we need the proper materials. The material Kelvin and I used for this lab are the PASCO car with a mass of .25kg or 250 g ,a track a black smart pulley with a radius of 0.025 meters, an Apple MacBook Pro, string to a desired length, a hook with washers approximately 6 grams each, USB connector, scissors to cut string to appropriate length, and Earth with a gravity of 9.8 m/s
Lab Procedure
Initially, we set up our track from some desirable point from the table and we made it touch the top of the edge of the table. We placed the car at the beginning of the track which was tied to a tight string. The string was running over the pulley and was holding the washers on the other end at a certain height. The car’s height didn’t really matter because it wasn’t changing at all throughout the lab. Each data run, I let the car go and it would go until the washers hit the ground. Kelvin watched the washers and when they hit the ground he would press stop before they hit to find the maximum velocity at that
