This set of 14 solid balls measuring 25mm in diameter are perfect for conducting a range of physics experiments exploring collision. Using inclined planes, momentum and accelration, you can demonstrate the conversion of potential energy to kinetic energy. Included are two balls each of different materials (wood, brass, copper, iron, steel, aluminum, and zinc); the differing densities of each pair will provide different results when used in varying combinations during collision experiments. Great for science fair projects involving physics or hands-on experiments in the classroom
