Force Mechanism Trough
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.
Hook's Law Apparatus
This sturdy Hooke's Law apparatus features a mirrored scale to eliminate parallax error.
Collision Track
This track includes everything needed to demonstrate three basic concepts of physics: acceleration, collision, and force.
Density ID Set
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.
