This is the rotating apparatus that we used for the lab experiment.
Explanation: After we set up the rotating apparatus, we connected it to LoggerPro for it to read the information. We also configured LoggerPro in the form given in the lab sheet, so we would get accurate data. Then, we attached a string into the rotating apparatus and a mass with certain weight. We ran the experiment a series of times, releasing the mass from a high point, so that the mass would accelerate downwards. We changed the equipment, such as torque pulley, top disk, and weight of hanging mass a couple of times to see how the acceleration would change in each experiment.
This picture shows the data table obtained when we ran the experiment for the first time, our idea was to use the velocity vs. time graph and find its slope, which would give us the acceleration of the system.
This is the graph velocity vs. time for the first trial.
This is the graph of velocity vs. time for the double weight of the hanging mass.
This is the graph velocity vs. time obtained for tripling the mass of the hanging object.
This is the graph we obtained by changing the size of the torque pulley.
These are the values that we got for each type of experiment. We did six of them, and we got the graph for four of them, the other two we didn't take a picture of the graph because they all look familiar, except for the value of the slope.
Summary: We can say that this lab was successful because we found out that by doubling the mass of the object, the acceleration also doubled, and tripled when we used 3x the hanging mass. When we switched the top steel disk into and aluminum disk, we got an acceleration that was about 5 times faster that with using the steel disk. When using the large torque pulley, the acceleration doubled. By looking at this, we can conclude that there exists a relationship between the torque pulley, the rotating disk and the weight of the object with the acceleration of the system.
