Unlike traditional pendulums, the Kater's pendulum center of gravity does not have to be know in order to determine the acceleration due to gravity.

Fun, Hands-On, and Safe Exploration of Force

These springs are an oversized demonstration of Hooke's Law.

This sturdy Hooke's Law apparatus features a mirrored scale to eliminate parallax error.

This track includes everything needed to demonstrate three basic concepts of physics: acceleration, collision, and force.

Measures velocity and acceleration with durability and accuracy.
