1. Make a graph of T (time for one oscillation, in seconds) vs. length (in m). T is on the y-axis. What type of mathematical relationship seems to represent the data?
2. Look up an equation for "period of simple pendulum". What type of curve does this equation suggest? Does your data seem to represent this?
3. How could you tell how "good" your data is? How can you test it in relation to the equation above? Try it, if possible.
