Great for studying the simple harmonic motion of a torsional pendulum.
- Designed to study the simple harmonic motion of a torsional pendulum
- Demonstrates torsional pendulum constant dynamically as well as in the static case
- Approximately 22.5" in height
- Great for physics classrooms
The torsional pendulum is an angular version of a simple harmonic oscillator. Instead of back and forth motion like in the case of a spring, the restoring force is actually a restoring torque, causing the pendulum to rotate backwards to equilibrium.
This kit explores the two distinct ways to determine the torsional spring constant of the wire; one that involves a dynamic system, like a regular pendulum swinging back and forth, and the other, a static system, akin to one way of measuring the restoring force of a spring.
