The EJS Faraday Loop Changing Field Model shows the induced emf in a changing external magnetic field. You can control the frequency, magnitude and type of variation in the external field as you would in the laboratory when using a function generator to produce current in a large coil. You can...

The Kicked Rotor model shows the dynamics of a rotating bar (rotor) that is kicked periodically. This model is also known as the standard map or the Chirikov-Taylor map. Each impulsive kick changes the angular momentum of the rotor instantaneously and the bar rotates uniformly between kicks.... Platforms: Mac

The EJS Cellular Automata (Rule 90) model displays a lattice with any one of a finite number of states which are updated synchronously in discrete time steps according to a local (nearby neighbor) rule. Rule 90 is a specific nearby neighbor rule following the classification scheme developed by... Platforms: Mac

The Rectangular Well model displays the 2D energy eigenstates of a particle trapped in a very deep two-dimensional rectangular well. Because the Schr?*A*dinger equation for this system is separable into one-dimensional infinite square well Hamiltonians, the solution can be expressed as a product... Platforms: Mac

The Ejs Orbiting Mass on a Table 3D model displays the frictionless dynamics of two masses that are attached via a string through a hole in a horizontal table. Mass m moves on the table in two dimensions while mass M hangs vertically and just moves up and down. The simulation allows displaying... Platforms: Mac

The EJS Angular Acceleration of a Contracting System model shows a mass and pulley system to illustrate what happens when a rotating system contracts. When the centripetal force has contracted a rotating system to half its initial radius then: (1) The tangential velocity has doubled, (2) The... Platforms: Mac

The EJS Slipping and Rolling Wheel Model shows the motion of a wheel rolling on a floor subject to friction. The simulation allows the user to change the initial translational and rotational velocities of the wheel, v and ?Ya*, the mass, radius, and mass distribution, R, m, and C of the wheel. By... Platforms: Mac

The Circular Well model displays the 2D energy eigenstates of a particle trapped in a very deep two-dimensional circular well. Because the Schr?*A*dinger equation for this system is separable into radial and angular differential equations, the solution can be expressed as a product of a Bessel... Platforms: Mac

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. The height of the gnomon and its shadow length are displayed in Earth radius units. It is a supplemental simulation for an article by Barbara... Platforms: Mac

The EJS Ballistics and Orbits model displays ballistic trajectories near the Earth. The model shows the trajectory with respect to the inertial coordinate system and the trajectory as seen from a point of view that is co-rotating with the Earth. You can examine and modify this simulation if you... Platforms: Mac

The Foucault Rod model displays the vibration of a circumnavigating rod. One end of the rod is firmly secured to a support. The free end of the rod has a weight attached, like the bob of a pendulum. The support of the rod is circumnavigating a central axis. The plane of swing of the Foucault rod... Platforms: Mac

Elastic Bounce on an Inclined Plane Model written by Juan Aguirregabiria The Elastic Bounce on an Inclined Plane model can be used to illustrate the adiabatic theorem in classical mechanics. A particle slides without friction along an inclined plane. The particle rebounds elastically when it... Platforms: Mac
