Computational Resources for Teaching

The OSP Collection provides curriculum resources that engage students in physics, computation, and computer modeling. Computational physics and computer modeling provide students with new ways to understand, describe, explain, and predict physical phenomena. Browse the OSP simulations or learn more about our tools and curriculum pieces below.


The Tracker tool extends traditional video analysis by enabling users to create particle models based on Newton's laws. Because models synchronize with and draw themselves right on videos of real-world objects, students can test models experimentally by direct visual inspection.

Featured Tracker Package

Featured OSP Resource

Deflating Soap Bubble
A Tracker experiment that uses video analysis tool to study the rate at which a soap bubble shrinks as it deflates through a capillary tube. Combining this data with an independent determination of the surface tension of the soap solution enables you to determine the viscosity of air.

Curriculum Packages

OSP curriculum packages combine computer simulations with tutorial materials and student worksheets. Packages can be modified to meet the needs of faculty and students

Featured Curriculum Package

Featured OSP Resource

Introductory Astronomy Models
A shared file folder of Astronomy models designed for a college-level introductory astronomy course.  This shared folder contains over 50 EJS models and is broken up into three parts: naked-eye astronomy, classical astronomy (optics and orbits), and modern astronomy.

EJS Modeling

Student modeling, the guided exploration of physical systems and concepts, is a powerful approach to engaged learning. Easy Java Simulations provides the computational tools for students and faculty to explore physics without the need for learning details of java programming.

Platform on Two Rotating Cylinders Model
The Ejs Platform on Two Rotating Cylinders model displays the model of a platform resting on two equal cylinders are rotating with opposite angular velocities.  There is kinetic friction between each cylinder and the platform.    The separation between the cylinders and the coefficient of kinetic friction can be changed via textboxes.
