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.

Projectile Motion with Angry Birds
The Projectile Motion with Angry Birds lab uses the original video from Rovio, the makers of Angry Birds and the Tracker video analysis tool to measure and analyze the motion an angry bird projected from a slingshot to hit a pig. This OSP item was inspired by Rhett Allain's Dot Physics, a physics blog for Wired.

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

Ghostly Images JS Package
The Ghostly Images Package contains Javascript models and worksheets for 1D kinematics to illustrate the connection between motion diagrams ("ghostly images") and position-time plots. Simulations include constant velocity and constant acceleration. Developed for the Physical Science classroom.

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.

Wheeler's Delayed Choice Experiment Model
This simulator implements  the Wheeler's Delayed Choice Experiment in an ideal Interferometer of Mach-Zehnder type, as desccribed by John Archibald Wheeler and Wojciech Hubert Zurek,  Editors in "Quantum Theory and Measurement" , Princeton Series in Physics, (1984).

The simulator shows  the basic fundamental  ideas of the Quantum Mechanics:

    Wave-Particle nature of Photon
    Probabilistic interpretation of  Quantum Mechanics
    Superposition of Quantum States in Beam Splitting
    Interference of states in One Photon experiments
    The striking difference between  Photons and Classical  
    particles, i.e. between Quantum Mechanics and Classical
    Common Sense intuitions


Open Source Physics provides extensive resources for computational physics and physics simulations. Included are:

  • An Eclipse environment for OSP
  • OSP Source Code Libraries
  • OSP best practices
  • Documentation

Access programming resources


OSP provides several general applications for physics teaching, student activities, and curriculum distribution. These are:
