Unformatted text preview: Experiment 11 Work and Energy on an Air Track Introduction In this experiment, we will make use of a glider and a sonar range finder on an air track to record the distance the glider will go at different times up to 10 seconds in order to estimate gravity. Using an Ultrasonic Measurement System in a computer program we can find the distance at each time. In investigation one, the air track will be on an incline by placing a block underneath on one side. The glider is placed about 20 cm away from the motion sensor before releasing it, to record our results. The computer program will record the distances every .1 seconds for 10 seconds. The time and position of the glider will then be recorded into a data table. From the data we collected, we then will calculate the velocity, average position, velocity squared, and error in the velocity squared. The position vs. time and velocity squared vs. average position will then be plotted. For investigation two, the air table will be level. The glider will move horizontally being pulled by a weight that will be moving vertically. The weight is attached by a piece of paper which will be suspended over the pulley and attached to the glider. The same way we found our data from investigation one will be used for investigation two. We also plotted the same graphs from investigation one, but using our new data from investigation two. In investigation three we combine what we did in investigation one and two, by putting the air track on an incline and by using the pulley and weight. By using the same steps as in the first two investigations, we found the time and position and then will calculate the velocity, average position, velocity squared, and error in the velocity squared. We will also plot velocity squared vs. average position. Finally, in each investigation, we will calculate gravity (g) and compared it to the known value of gravity.
