Features 23 core lab activities that cover the fundamental concepts of Force & Motion, Energy Transfer, Electricity & Circuits, Fluids and more.

Simple Harmonic Motion

Lab Summary

Use a motion sensor to measure the period of a simple pendulum.

Theory

This activity introduces students to the simple harmonic motion of a simple pendulum. Students will:

  • Use a motion sensor to measure the period of a simple pendulum
  • Describe the energy conversions taking place during the pendulum's swing
  • Gain skills using scientific measurement tools
  • Conduct a scientific investigation including making and analyzing graphs, making
    predictions, and analyzing results

Method

Students gain experience conducting the following procedures:

  • Setting up the equipment and work area to measure the motion of a swinging pendulum
  • Making a simple pendulum from a soda bottle containing a volume of water as its mass
  • Measuring the period of the pendulum as it swings through a small angle and a larger angle, first at one mass and then at twice the mass
  • Using math skills to interpret the graphs of position versus time

Sensors / Equipment Used:

PASPORT Motion Sensor

(PS-2103A)

The PASPORT Motion Sensor accurately measures position, velocity, and acceleration of a target. Can be used to track the motion of carts, balls, people and more.
