CLEARANCE

Drilled balls are used for pendulum bobs or impact experiments, while our other balls are suitable for collision apparatus and density/volume experiments.

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

Present a Wide Variety of Standard Force and Motion Activities.

This large aluminum pulley is a great alternative for Atwood’s Machine experiments.

Identify All Three Classes of Levers and Their Key Parts

A set of 15 samples of different materials used to challenge students to identify materials based on measurement of their density. For some specimens this will be straightforward. In other cases, it will lead to a discussion of uncertainty in measurements and data, and to an awareness that different materials may have nearly the same density.

Explore Force, Acceleration and Hooke's Law. No tools required.

Nearly frictionless, accurate, durable.

Lightweight, tear-resistant parachutes in a variety of sizes.

High-speed pulley with low friction design mounted on a rod for easy integration into experiments.

Easy-to-assemble beginner level rocket with pre-colored parts.

With the Air Track, students can investigate motion phenomena at a precise level of measurement.

With the Force Mechanism Trough, students can research acceleration and the effect of gravity on a moving body by propelling steel balls or a wood block down an aluminum trough track.

This air track provides a frictionless surface that is indispensable for studying the mechanics of linear motion.

Easy-to-assemble intermediate-level rocket with laser cut balsa fins.

Intermediate-level rocket with five fiberboard fins and a streamer recovery system.
