OPTIKA Galileo’s Cart
Thanks to this cart it is possible to perform experiments on reference systems in translational motion. It is fitted with an electromagnet which holds a steel sphere at a level of 25 cm over the cart’s plane. The release of the sphere is controlled by a photocell which can be activated through a simple torch. The falling point of the sphere is imprinted on a strip of carbon paper, letting students check Galileo’s relativity principle for the systems in uniform and accelerated motion both on an horizontal and on an inclined plane.
