Set for Study of Rotational Movements


Quick Overview

Set for study of rotational movements. The most versatile and complete equipment on the market.

Its operation is based on a rotational paltaform with variable speed control. In it we set to turn a suspended body connected to a dynamometer that indicates the force to which the body is submitted. In addition to the experiments for determination of the centripetal force we can perform the circular motion experiments (uniform and variable).

It also includes the set of accessories for determination of the moment of inertia of solid bodies as well as the demonstration of the conservation of angular momentum and the acrylic vessel for rotational experiments in liquids. This equipment also has the AZB-30 USB stopwatch for time measurement through a raked disc thus leaving the most attractive and modern experiments.

To facilitate storage and storage of the equipment it is supplied with a thermoformed plastic cradle pack with the shape of the parts.

- Three functions:  

  • F1 [measuring the time interval between the sensors, coil and sensor and switch and sensors, set up to select the number of sensors to be used in experiment];
  • F2 [Measurement interruption time of 1 sensor or both sensors or measurement time between sensors];
  • F3 [measuring time by the number of sensor interrupts with the number of interrupts setting for the measuring period pendulums or swirling];  

Data Acquisition Software AZB-30 USB 

Minimum requirements: 

  • Windows 7, Windows 8.1, Windows 10, 32- or 64-bit
  • Processor 500 MHz or higher (Windows 10 requires a 1 GHz processor)
