Converting Mechanical Energy into Heat Energy – Recording and Evaluating with CASSY
These experiments P2.3.3.1 und P2.3.3.2 show the equivalence of mechanical and heat energy. A hand crank is used to turn various calorimeter vessels on their own axes, and friction on a nylon belt causes them to become warmer. The friction force is equivalent to the weight G of a suspended weight. For n turns of the calorimeter, the mechanical work is thus
