Inertia

Inertia Demonstrator

Perform a classic experiment and always get results with this rugged and reliable inertia demonstrator. A 22 mm diameter steel ball rests on a thin metal card on top of a pillar. A spring-loaded ca... More.

Liquid Accelerometer

Visualize inertial movement with this low-cost device. Demonstrate gravitational and uniform acceleration. Illustrate acceleration down an incline plane. Horizontal acceleration creates characteris... More.

Moment of Inertia Ring

Demonstrator is based on the classic ring and disk. The shatterproof ring has a rod with two positionable masses mounted to it. The moveable masses allow the moment of inertia to be varied. Compari... More.

Ring and Disc

A fast, foolproof middle school lab! Simple materials, each with the same mass (±2 grams) and diameter - a PVC plastic ring and hardwood disc demonstrate mass distribution in rolling bodies. R... More.

Inertia Ball

Stretch your science budget - one ball, two ways to use it! Use this heavy-duty zinc ball as a sturdy pendulum bob. Simply screw in one eyebolt and attach a string at one end. Use both eyebolts if ... More.

Inertia Apparatus

The acrylic ball rests on the card - when you pull back the spring, the card shoots forward, but the ball returns to its perch on the post. This device illustrates the effect of inertia. To the obs... More.
