Factors Affecting Frequency
Factors Affecting Frequency

Two experiments. Choose one. In the first, students are guided through the process of testing 3 variables; mass, length, and amplitude; to determine which affects the frequency of a simple pendulum. In the second, students use inquiry and experimental design...

Graphing Pendulum Motion
Graphing Pendulum Motion

Students predict and then measure, using a motion sensor, the changing position, velocity and acceleration of a simple pendulum. Graphing the motion leads to a discussion of the total force on the pendulum at different points in its motion. Download...

Physical Pendulum
Physical Pendulum

A pendulum with its mass spread throughout its length is called a physical pendulum. A typical clock pendulum is an example. Students will observe a physical pendulum and measure its period, and then construct a simple pendulum with the same...

Simple Pendulum
Simple Pendulum

Students will test two variables, to determine their effect on the pendulum's period. Just as objects with different masses accelerate in free-fall at the same rate, changing the mass of a simple pendulum will not change its period. Changing the...
