Properties of Pendulums

Objective

To understand the properties of pendulums and how they can be used as timekeepers.

Difficulty

Procedure: Medium

Concept: Medium

Concept

Pendulums have been used for timekeeping for hundreds of years because of its properties.The swing of the pendulum is called an oscillation. There are several factors that effect the oscillation and in this experiment you will explore the effects of mass and length.

Materials

Hypothesis

How will adding more weight effect the pendulum? How will length of the string effect the pendulum?

Procedure

Analysis

Calculate the averages for each trial and plot your results. Did the mass effect the rate of the pendulum? How did the string effect the rate of the pendulum?

Extensions

Explore the properties of pendulums. What else effects the the rate of a pendulum? How can you test it?
