Pendulum revisited

Use the data for the pendulum period versus the length.

Plot a graph of period versus length. Remember unit and axis labeling.

Is there a mathematical relationship that you can see?
Can you predict what an equation (of period versus length) might resemble?

Look up the following:

Period of a simple pendulum.

Usually, period is represented by a T, in seconds, and length is given as L (in meters). See if you can find an equation for this relationship.

Does this equation seem correct for your graph?

In general, this is a good place to start for class research:

If you use this site, start with the physics tutorial link, and look for waves - and then Vibrations (and pendulum motion).

For next class, bring in a graph and your other findings.

Good luck!
