Ping Pong Ball Experiment[edit]

    The goal of this experiment was to calculate the distance and time of a ping pong ball rolling down toy tracks to see if the ball stops based on air drag or friction. After calculating the distance and time, we calculated the velocity and acceleration based on our data.
Describing the Experiment[edit]
    We connected toy tracks until they reached about 3 meters long. Next, we placed one end of the track onto stacked metal blocks, approximately 2.5 inches tall. We then proceeded to place the ping pong ball on the raised end of the track. Once the ball was place, it was then let go. The ball then rolled down the tracks at a slight decline until it reached the flat portion of the tracks. Once the ball reached the flat surface, time started to be recorded. The ball was measured every 2 seconds. Each group member marked the distance the ball traveled every 2 seconds until 8 seconds passed. 
Calulations[edit]
    The figure below shows 2 different graphs with different calculations. The calculations on the left are based on the total inches accumulated over a set period of time. The calculations on the right are based on the distance between each set interval (Example: interval 0-2, 2-4, 4-6, 6-8).
    In both the left and right, the velocity and the acceleration were calculated and displayed along with the distance and time. The graphs of each scenario are also displayed.

Modified Motion Detector Report[edit]

    Contributed by 006, 012, 009, 002
    The report lacked a good conclusion, so a conclusion will be our only edit to Jan's report on the motion detectors.
Conclusion:
    In the real world, we will need to use data to find certain parameters in the application of Physics. For example, the position and velocity were measured using the motion detectors. We can calculate these by hand using the mathematical concept of derivatives. With being able to prove that derivatives work between the velocity and position, it helps in our understanding of certain aspects of motion.
