## What does the period one complete to and fro of a pendulum such as swing depend on quizlet?

Galileo discovered that the time a pendulum takes to swing to and fro through small distances depends on only the length of the pendulum. the time of a to-and-fro swing, called the period, does not depend on either the mass of the pendulum or the size of the arc through which it swings.
