Gnomon Model v.1.0
Gnomon shadow simulation to help you with your studies. The EJS Gnomon model simulates the shadow cast by a gnomon (the part of a sundial that casts the shadow) over the course of a day for any day of the year and any latitude on Earth.
Coupled Oscillators and Normal Modes Model v.1.0
Analyze coupled oscillators motion with this tool. Coupled Oscillators and Normal Modes model displays the motion of coupled oscillators, two masses connected by three springs. The initial position of the two masses,
QM Momentum Measurement v.1.0
Study the position-space wave function with the help of this simulation. QM Momentum Measurement software displays the time evolution of the position-space wave function and can be used to simulate the quantum-mechanical measurement of momentum.
Noon Shadow Model v.1.0
Analyze the shadow cast by a gnomon at noon with this tool. The Noon Shadow model shows the geometry of the shadow cast by a gnomon at noon. Users can change the orientation of the gnomon as well as its latitude.
Approach To Equilibrium v.1.0
Equilibrium simulation to help you with your studies.
Radioactive Decay Events v.1.0
Decay of a radioactive sample simulation to help you with your studies. The EJS Radioactive Decay Events Model simulates the decay of a radioactive sample using discrete random events.
QM Carpet Program v.1.0
Study the position-space wave function with this tool. QM Carpet software displays the time evolution of the position-space wave function and the associated quantum-mechanical spacetime diagram, the quantum carpet.
Hertzsprung Russell (H-R) Diagrams v.1.0
Hertzsprung-Russell (H-R) Diagrams model simulates Hertzsprung-Russell (HR or H-R) diagram for groups of stars. The diagram is a scatter plot of steller luminosity vs. stellar temperature.
Twin Paradox Program v.1.0
Analyze the time dilation effect with this simulation. Twin Paradox software displays the effect of time dilation on a moving twin as seen from a stationary twin.
RLC Circuit Model v.1.0
Study electricity and magnetism with this simulation. RLC Circuit model simulates a resistor,
