"Interactive Physics is exciting...This program definitely sets the standard for modeling physical systems on the computer"
- Paul Hewitt, author of Conceptual Physics

Create, run, and change experiments not possible or practical in the lab. Perhaps the most widely known educational physics simulator, IP includes a library of over 150 ready-to-run experiments. Create models; add objects like springs, dampers, and ropes; measure attributes of your objects like velocity, acceleration, momentum, and energy. Display these measurements as numbers, graphs, or animated vector displays.

The Workshop Projects acquaint new users with the available tools and get them started with six simple experiments. Users can attach images to the objects they create and add sound effects or sound measurements to their experiments.

Besides building models, Interactive Physics lets you and your students take important measurements while a simulation runs. You can:

  • Measure physical quantities such as velocity, acceleration, momentum, angular momentum, kinetic, and friction.
  • Display measurements as numbers, graphs, or animated vector displays.
  • Model Newtonian mechanics
  • Alter friction and elasticity
  • Change gravity or even turn it off
  • Control almost any physical characteristic of an object
  • Create models and simulations limited only by your imagination

Interactive Physics is Easy-to-use!

  • No programming required
  • Build models by drawing on the computer screen
  • Springs, ropes, dampers, slots, joints, pulleys, actuators, meters, buttons, sliders, and mass shapes are all available
  • Assign parameters to specify conditions for a simulation
  • Click RUN to animate the model under these specific conditions
  • Interactive Physics accurately determines how objects should behave while presenting a realistic simulation.

Supports State-of-the-Art Pedagogy

Interactive Physics offers powerful tools for modern learning:

  • Simulations that develop inquiry skills and physical knowledge
  • Model-building for active, constructive problem solving
  • Animation helps students visualize abstract concepts
  • Multiple representations that support different learning styles

Interactive Physics is the perfect complement to traditional physics instruction.

  • Illustrate concepts and principles in lectures
  • Simulate difficult, end-of-chapter problems
  • Compare simulation results with symbolically-derived solutions
  • Interactive Physics' modeling and simulation capabilities are especially compatible with inquiry learning.

"In tutoring Middle School students to teaching graduate students at Stanford, I find Interactive Physics is to Physics as a calculator is to math." -Paul Mitiguy, Prof. of Physics - Stanford University


Information regarding Interactive Physics licensing options. There are two types of licensing available to run the Interactive Physics Software.

Single User (commonly referred to as "Traditional" or "Node Lock")

Choose single-user licensing when you need the program to be installed and run directly on individual workstations. No dedicated server is required. This type of licensing can be used off-site where no connection to a network is needed.

A license must be purchased for every computer where the software is to be run.


This type of licensing uses a dedicated server to be shared amongst any number of workstations. The number of students using the software at a given time must not exceed the number of licenses purchased.

Explore the simulation below on Projectile Motion

Use the buttons and controls to run the simulation and change the parameters of the launch. You'll need to allow Active-X to run on your browser to view the applet.

With more than a million users and in 11 languages, Interactive Physics is breathing life into the world of physics!
