PheT Interactives
"Overview: Simulate the original experiment that proved that electrons can behave as waves. Watch electrons diffract off a crystal of atoms, interfering with themselves to create peaks and troughs of probability. Subject: Physics Level: High School Material T...

Projectile Motion
"Overview: Blast a Buick out of a cannon! Learn about projectile motion by firing various objects. Set the angle, initial speed, and mass. Add air resistance. Make a game out of this simulation by trying to hit a target....
Signal Circuit (AR)
"Overview: Why do the lights turn on in a room as soon as you flip a switch? Flip the switch and electrons slowly creep along a wire. The light turns on when the signal reaches it. Subject: Electronic Technology Level:...
The Ramp
"Overview: Explore forces, energy and work as you push household objects up and down a ramp. Lower and raise the ramp to see how the angle of inclination affects the parallel forces acting on the file cabinet. Graphs sho...
Molecular Motors
"Overview: Discover what controls how fast tiny molecular motors in our body pull through a single strand of DNA. How hard can the motor pull in a tug of war with the optical tweezers? Discover what helps it pull harder....
Nuclear Fission (AR)
"Overview: Start a chain reaction, or introduce non-radioactive isotopes to prevent one. Control energy production in a nuclear reactor! (Previously part of the Nuclear Physics simulation - now there are separate Alpha D...
Resistance in a Wire (AR)
"Overview: Learn about the physics of resistance in a wire. Change its resistivity, length, and area to see how they affect the wire's resistance. The sizes of the symbols in the equation change along with the diagram of...
Radiating Charge
"Overview: The 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 (br...
Normal Modes
"Overview: Play with a 1D or 2D system of coupled mass-spring oscillators. Vary the number of masses, set the initial conditions, and watch the system evolve. See the spectrum of normal modes for arbitrary motion. See lo...
Quantum Bound States
"Overview: Explore the properties of quantum ""particles"" bound in potential wells. See how the wave functions and probability densities that describe them evolve (or don't evolve) over time. Subject: Physics Level: Hi...
Davisson-Germer: Electron Diffraction
"Overview: Simulate the original experiment that proved that electrons can behave as waves. Watch electrons diffract off a crystal of atoms, interfering with themselves to create peaks and troughs of probability. Subjec...
