Apparatus for the Analysis of Rotational Motion

It’s rare to find in a physics laboratory, the equipment for a complete study of the rotational motion laws.  This argument, in fact, is usually overshadowed by the study of linear motion. This item allows the study of both rotational and linear uniformly accelerated motion, by using a stopwatch (not included in this kit). If you have a data acquisition system with a distance sensor, you can refer to the last chapter of the didactic guide which explains how to use this tool for the study of the rotational motion. We recommend our model code 9066. The application fields of the experiments available with this device are various, such as: - to become acquainted with the angular quantities characterizing the rotary motion; - to learn how to recognize the formal similarities between the Laws of rectilinear and rotary motion; - to learn how to measure the inertia moment of the bodies or of a masse’ distribution; - to verify the conservation principle of energy. In absence of losses, the variation of the plate’s potential energy has to be equal, in each moment, to the sum of the plate’s translational kinetic energy plus the rotational kinetic energy of the disc or of the balancer: I0 is the mass-centered inertia moment and ω is the angular speed.  The graph below shows the potential energy variation in green, the rotational kinetic energy in blue, the translational kinetic energy in magenta and the total energy in red. The translation energy is insignificant due to the small mass and the low speed. In addition, the total energy is not constant but it is subject to a slow decay caused by inevitable friction. EXPERIMENTS: - Uniform circular motion and harmonic motion - Kinematics of rotational motion - Similarities between translator and rotational motion - The dynamics of rotational motion  - The fundamental law of rotational motion - The moment of inertia - The kinetic energy of rotational motion - Conservation of mechanical energy - How to use the distance sensor
