Ptolemy/Copernicus/Tycho EJS Model v.1.0
Comparison between three famous planetary models. Ptolemy/Copernicus/Tycho EJS Model illustrates the relationships between the systems of planetary astronomy developed by Claudius Ptolemy, Nicholas Copernicus, and Tycho Brahe.
Polarizer Program v.1.0
Plane polarizer effect simulation. Polarizer software displays the effect of a plane polarizer on an incident electromagnetic wave. The polarization of the electromagnetic wave and the orientation of the polarizer can be modified.
Point Charge Forces in 2D Model v.1.0
Study electricity and magnetism with this simulation. Point Charge Forces in Two-Dimensions model investigates the electric force that a charged particle experiences in a two-dimensional situation, because of four other nearby charged particles.
Platform on Two Rotating Cylinders Model v.1.0
Study classical mechanics with this simulation. Platform on Two Rotating Cylinders model displays the model of a platform resting on two equal cylinders are rotating with opposite angular velocities.
Plane Wave: Step Scattering v.1.0
Plane Wave: Step Scattering is a quantum physics simulation. Plane Wave: Step Scattering model simulates the time evolution of a free-particle plane wave in position space when it is incident on a potential energy step.
Physical Pendulum Forces v.1.0
Gravitational forces simulation. The Physical Pendulum with Forces model displays the gravitational, normal, and friction forces acting on a mass attached to a pivoted rod.
Physical Pendulum Energy v.1.0
Study rotational dynamics with the help of this simulation. Physical Pendulum Energy model shows the motion of of a physical pendulum (rod) and and the kinetic and potential energies of the parts of the rod above and below the rotation axis,
Photoelectric Effect v.1.0
Analyze the Photoelectric effect with this tool. Photoelectric Effect model simulates the Photoelectric effect discovered by Hertz in 1887 and described theoretically by Einstein in 1905. Light of a given frequency (and energy) shines on a metal.
Phases of Venus Model v.1.0
Simulate the Venus phases with this tool. Venus Phases model shows the shadows cast by two gnomons at different locations on Earth.
