Here is a unique way to study horizontal and vertical motion, conservation of energy, and momentum! A track mounted to a vertical board directs one or two carts, casting them into a free-fall. The angle of the track is easily adjustable. A pen projecting from the back side of the carts marks the path of the cart on a piece of graph paper mounted to the vertical board as it falls. The pen can be refilled with any standard ink. The graph paper is held in place with magnetic strips, which enables quick replacement for the next student’s use. Add weights to the carts to study the effects of increased mass on momentum. Ideal for use in classroom demonstrations.
These goggles meet the American National Standards Institution (ANSI Z87.1) and Canadian Standards (CSA Z94.3) regulations.
