fischertechnik Dynamic - Fun with Physics
From the Manufacturer With this set, students can build 6 different track based models to learn about and observe first-hand various physical phenomena, such as Acceleration Inertia of Mass Centrifugal Force Law of Conservation of Energy Principle of Linear Momentum Laws of Motion Physics becomes fun as balls race on the unique flex-rails through various obstacle courses. They accelerate, decelerate, cause chain reactions, shoot through the loop and run through obstacles such as teeter-totters and switches. An elevator powered by a fischertechnik XS Motor conveys the balls to the top. The effects of each of these principles are explained in the enclosed activity booklet and can be clearly demonstrated using various experimental set-ups. WARNING Electronic parts contain lead. May
