Bell Ringer: Pendulum Period and Length

Published on 08/24/2010

Activity Overview

Students analyze data from a swinging pendulum to determine the formula for the period of a pendulum using regression and dimensional analysis.

Key Steps

  • Image

    Students study the relationship between a pendulum's length and its period.

     

    First, they examine a graph of pendulum position vs. time and determine the pendulum's period.
