Curriculum Module

Created with R2021a. Compatible with R2021a and later releases.

Information

This curriculum module contains interactive MATLAB® live scripts that explore one-dimensional collisions using a virtual air track. The air track can be configured to model elastic or inelastic collisions.

Background

image_0.png

You can use these live scripts as demonstrations in lectures, class activities, or interactive assignments outside class. This module covers elastic and inelastic collisions. It also includes examples of energy conservation. The live scripts contain instructions for conducting experiments using the virtual air track. The instructions include theory, pre-lab, virtual experiment, and data analysis sections. The law of conservation of momentum is studied by simulating elastic and inelastic collisions. The law of conservation of energy is studied by attaching a hanging mass to one of the carts.

The instructions inside the live scripts will guide you through the exercises and activities. Get started with each live script by running it one section at a time. To stop running the script or a section midway (for example, when an animation is in progress), use the image_1.png Stop button in the RUN section of the Live Editor tab in the MATLAB Toolstrip.
