Students examine the motion of pendulums and come to understand that the longer the string of the pendulum, the fewer the number of swings in a given time interval. They see that changing the weight on the pendulum does not have an...

Learners study the work and accomplishment of Galileo. In this physics lesson, students calculate the period of a pendulum's using a mathematical equation. They explain the different factors affecting its period.

Students explore how pendulums work and why they are useful in everyday applications. In a hands-on activity, they experiment with string length, pendulum weight and angle of release.
