Centripetal Force Set


Quick Overview

Set for study of rotational movements. Its operation is based on a rotational platform with variable speed control. We put it to turn a body suspended connected to a dynamometer which indicates the force which the body is subjected.
In addition to the experiments to determine the centripetal force we can accomplish circular motion experiments (uniform and variable).
Sold separately (see related products), the set of accessories for the moment of inetria of the solid bodies and conservation of angular moment, and an acrylic container for rotational experiments in liquids.

Sold in two different versions:

62001150 - With Digital Stopwatch AZB-30 USB and Photoelectric Sensor
62001078 - With Manual Stopwatch

- 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)
