Rotary Motion Sensor – Physical Pendulum Set

Product Code: ME-9833


This set of six objects is perfect for studying Physical Pendulums, Moments of Inertia, and the Parallel Axis Theorem. Each piece fastens directly to a Rotary Motion Sensor to measure the object’s acceleration due to an applied torque, or the period when the pendulum freely oscillates.

Each piece is made from 1/4 inch-thick aluminum plate.

How It Works

Apply a known torque and measure the angular acceleration to calculate the moment of inertia of the object. Multiple holes in the plate allow investigation of the Parallel Axis Theorem.
