Complete Rotational System - ME-8950A

ME8950A_MAIN.jpg

Overview

PASCO's Complete Rotational System provides a range of experiments in centripetal force, angular momentum and rotational motion. A unique set of accessories makes it an ideal tool for experiments in torque, friction, magnetic levitation and Faraday's Law.

Experiments Featured in the Instruction Manual

  • Rotational Inertia of Disk and Ring -- Two Axes
  • Centripetal Force
  • Rotational Inertia of Off-axis Disk (fixed and rotating)
  • Conservation of Angular Momentum, Using a Point Mass
  • Rotational Inertia of a Point Mass
  • Conservation of Angular Momentum, Projectile Version
  • Conservation of Angular Momentum, Using Disk and Ring

Features

The differences in moments of inertia are large enough to be sensed by the student when rotating the system by hand.  Hardware fittings support mounting sensors for computer monitoring of angular position, velocity, and acceleration. A motorized rotational drive can be attached to the system to rotate the platform at any selected constant velocity.

  • Four kilogram cast iron base for stability
  • Dual ball bearings
  • Precision stainless steel shaft

How It Works

It is easy to implement computer-based data collection and analysis of rotational motion data with the Complete Rotational System with either a Rotary Motion Sensor or a Photogate. 

  • The Rotary Motion Sensor mounts to the base with an "A" Adapter and measures both angular velocity and direction
  • The Photogate Head mounts directly to the rotating platform base to measures angular velocity (the photogate does not determine direction).
