Suggestions for EXPERIMENTS

Measure the period of oscillation. How does it depend on the length of the pendulum, the accelaration of gravity, and the amplitude of oscillation?
Click here to get some hints about measuring the period.

Manipulate the parameter in such a way that the pendulum rotates either clockwise or counter clockwise.
What happens if you start the pendulum exactly in the upside-down position (i.e., the initial angle is just 180°)?
