With the new “Acceleration Lab” tab in the Forces and Motion: Basics simulation, students use an acceleration meter and a bucket of water to explore the concepts of speed, acceleration and net force, and learn how they relate to Newton’s Second Law of Motion: F=ma.
PhET is one of many providers of “Open Educational Resources” (OER) and is a big supporter of the larger open education movement. This week brings many opportunities to learn more about OER projects and the opportunity for OER to impact teaching and learning worldwide. See their list of events here:
With the new Radiating Charge simulation, you can learn how electric field lines from a point charge evolve in time as the charge moves. Watch radiation propagate outward at the speed of light as you wiggle the charge. Stop a moving charge to see bremsstrahlung (braking) radiation. Explore the radiation patterns as the charge moves with sinusoidal, circular, or linear motion. You can move the charge any way you like, as long as you don’t exceed the speed of light.
We’re excited to add another simulation to our growing mathematics collection. With the new Graphing Lines simulation, explore the world of lines. Investigate the relationships between linear equations, slope, and graphs of lines. Challenge yourself in the line game!
If you’re running Java 7, we strongly encourage you update to Java Update 13 (build 1.7.0_13-b20). This latest Java release includes critical security patches and makes running Java in the browser more safe.
Get the upgrade here:
And if you’d like to learn more about the update, read about it here:
Note to Mac Users: to run our 3D simulations, Molecule Shapes or Plate Tectonics, you will still have to downgrade to Java 6 as described in our previous blog.
Well, try again! We’ve upgraded both to work on as many platforms as possible. Please note that the simulations use LWJGL for the 3D graphics. Unfortunately, at this time LWJGL does not support Java 7 on Mac OSX. For to run these simulations, it is necessary to downgrade your Java to version 6. To learn how to do this, see
If you’re still having troubles, please let us know so we can ensure that it works for everyone.

See Tim Holt on El Paso Independent School District’s (EPISD) Digital Discoveries show how they use PhET.
PhET, December 9, 2011: “In this segment, we look at some amazing online simulations for science and math classes: PhET simulations. These are great for use on IWBs as well as for reinforcing concepts. We sample a few random PhET simulations, including John Travoltage!
