Overview

Manuals

Our Wilberforce Pendulum adds something extra to the traditional spring and mass pendulum--the Photogate Wheel enables electronic measurement of both modes of oscillation.
Now your students can observe the behavior of the pendulum and simultaneously see a live graph of its motion and the spring force as it changes back and forth from translational and torsional modes of oscillation.

How It Works

The motion of the Wilberforce Pendulum can be recorded using DataStudio software. The vertical position, velocity and acceleration are measured with a Motion Sensor placed below the pendulum. A Laser and a Laser Switch measure the angular speed in the torsional mode as the spokes of the wheel break the laser beam. The transition between modes can be seen on a graph. A Force Sensor attached to the end of the spring measures the spring force as the pendulum oscillates. The force can be graphed in real-time as a function of position to determine the spring constant and the theoretical period. The period of oscillation is about one second.
