Description

Overview

Our Rotary Motion Sensor may be the most useful sensor in physics! Use it to study optics, dynamics, centripetal force, motion of a pendulum and many other topics. Measures position, velocity and acceleration (angular and linear) with incredible (0.09 º) resolution and accuracy. Higher maximum spin rate (30 rev/sec) allows students to perform a full range of motion experiments.

  • Measures magnitude and direction of motion.
  • Ball bearings minimize friction and provide mechanical support to rotating objects.

Features

  • Three-step pulley (10, 29 and 48 mm diameter)
  • Rod clamp for mounting in almost any orientation

Typical Applications

  • Verify conservation of angular momentum
  • Calculate rotational inertia of disk ring and point mass
  • Measure displacement velocity and acceleration of a cart on a track
  • Conduct quantitative analysis of simple harmonic motion
  • Measure acceleration of a cart caused by a mass hung over a pulley
