Apparatus for the study of rotational motion OPTIKA SCIENCE

Apparatus for the study of rotational motion OPTIKA SCIENCE.

It is not common to find in the physics laboratory instruments for the complete study of the laws of rotational motion. This motion, in fact, is usually displaced to a second place with respect to the rectilinear motion.

This equipment that we present to you in Telescopiomania allows you to study either the rotational motion or the uniformly accelerated rectilinear motion using a stopwatch (not supplied with the apparatus). If you have a data acquisition system with a distance sensor it is possible to refer to the last chapter of the supplied manual where it is explained how to use this instrument for the study of circular motion.

The didactic interest of the experiments that can be performed with this apparatus allows the student:

• Become familiar with the angular magnitudes that characterize rotational motion
• Learn to recognize the similarities between the laws of rectilinear and rotary motion
• Learn to calculate the moment of inertia of bodies or of a distribution of masses
• To verify the principle of conservation of energy

Achievabletopics and experiments:

• Uniform circular motion and harmonic motion
• Kinetics of rotational motion
• Analogies between translatory motion and rotary motion
• Dynamics of rotary motion
• Fundamental law of rotary motion
• Moment of inertia
• Kinetic energy in rotary motion
• Principle of conservation of mechanical energy
• How to use the distance sensor
