Mass Time for 10 oscillations Period T (s) 1. 1 Q 3: Does changing the mass of the pendulum affect the period of oscillation? Explain. Q4. Summarize your results from table 1, 2 and 3. What factors affect the period of the pendulum and what factors do not affect the period? Q 5. Can we find any other factor that might affect the period? Look at the possible variables in the program and see if you can find another one to vary. Does this affect the period of oscillation? Explain clearly or show your data below to support your answer. 7. In Q6 you have found which variables affect the time period. Graphing is another way to see the relationship between variables. It can also show if the two variables vary linearly, inversely, quadratically, etc. Using the data from tables 1, 2 and 3, plot graphs of the following and figure out the relationship between the variables. Next to each of these, write down whether the relationship is linear, inverse, independent, quadratic or other. (a) Period T vs mass (b) Period T vs length of pendulum (c) Period T2 vs (length of pendulum) (d) Period T vs amplitude/angle
