Atwood's Machine Experiment - EX-5501

EX5501_MAIN.jpg

Overview

In this experiment designed for use with PASCO Capstone software, students use a very low mass/low friction pulley and measure the changing velocity of the unbalanced mass system. They interpret the slope of the velocity graph as accelerations. They examine the effect of the rotational inertia of the pulley and estimate the friction forces based on experimental data.

  • Newton's 2nd Law of Motion
  • Newton's 2nd Law of Rotational Motion
  • Rotational Inertia

The acceleration of the weights is determined using the slope of the velocity vs. time graph. From this, the acceleration due to gravity can be found.

PASCO Advantage

The Super Pulley/Photogate System makes it easy for students to set up the apparatus and take data. Analysis includes accounting for friction and the rotational inertia of the pulley.
