1. Determine the position in the oscillation where an object in simple harmonic motion: (Be very specific, and give some reasoning to your answer.) a. has the greatest speed
b. has the greatest acceleration
c. experiences the greatest restoring force
d. experiences zero restoring force
2. Describe simple harmonic motion, including its cause and appearance. (Make sure to use your own words, and be very specific. And few examples would be helpful.)
3. Use the information listed in Data Tables 1 to 3 to describe how the change in, using complete sentences:
a. amplitude (angle)
b. length
c. mass affect the period of the pendulum
4. Compare your calculations of g using individual measurements and using the graph in Graph 1, listed in Data Table 4. Do your measurements including uncertainty fall within the accepted value? Which method is more accurate? List possible sources of error in your data and calculations.
5. Was energy conserved during the motion of your pendulum? If not, list some possible ways energy could have been lost from the pendulum system, making sure to use complete sentences. 6. Why did you measure 10 periods of the pendulum instead of just 1? Would your measurements be improved by measuring 100 periods instead of 10? Why or why not? How many periods do you think is the optimal number to measure?
