Easy Java Simulations 4.3.5 Build 111211
A discrete computer simulation, or simply a computer simulation, is a computer program that tries to reproduce, for pedagogical or scientific purposes, a natural phenomenon through the visualization of the different states that it can have. Each of these states is described by a set of variables that change in time due to the iteration of a given algorithm.
All this means that EJS is a program that helps you create other programs; more...

The simulation displays a graph of the special function over the given range as well as the value of the selected function at a single point.The following special functions can be displayed:1. Legendre polynomials Pn(x)2. associated Legendre functions Pnm(x)3. Laguerre polynomials Ln(x)4. associated Laguerre...

Classical Helium Model 1.0
Classical Helium Model is a three-body problem simulation to help you with your studies. Classical Helium Model is an example of a three-body problem that is similar to the gravitational three-body problem of a heavy sun and two light planets. The important difference is that the helium atom's two electrons repel one another, unlike the planetary case where the intraplanetary interaction is attractive.The EJS Classical Helium Model was created...

Molecular Dynamics Model 1.0
Study molecular dynamics with this tool. Molecular Dynamics model is constructed using the Lennard-Jones potential truncated at a distance of 3 molecular diameters. The motion of the molecules is governed by Newton's laws, approximated using the Verlet algorithm with the indicated time step. For sufficiently small time steps dt, the system's total energy should be approximately conserved.This simulation was created by Wolfgang Christian using...

Harmonics and Fourier Series Model 1.0
Analyze harmonics sum fast and easy. Harmonics and Fourier Series model displays the sum of harmonics via a Fourier series to yield a new wave. The amplitude of each harmonic as well as the phase of that harmonic can be changed via sliders. In addition, several pre-set functions can be chosen to display. You can modify this simulation if you have Ejs installed by right-clicking within the plot and selecting "Open Ejs Model" from the...

QM Momentum Carpet 1.0
Position-space wave function analysis made easy. QM Momentum Carpet software displays the time evolution of the position-space wave function and the associated quantum-mechanical momentum-time diagram, the momentum-space quantum carpet. The default wave function is a Gaussian wave packet in an infinite square well. Additional states and other potential energy functions can be specified using the Display | Switch GUI menu item.QM Momentum...

Wave Packet Model 1.0
Approximate wave packet motion analysis made easy. Wave Packet model displays the motion of an approximate wave packet. The simulation allows an arbitrarily wave packet to be created. The default dispersion relation, with the frequency equal to the wavenumber, results in a wavepacket that does not spread. The amplitude, maximum and minimum wave numbers, the number of components, and the dispersion relation can all be changed via text boxes....

Circumnavigating Pendulum Model 1.0
Study mechanical oscillator dynamics fast and easy. Circumnavigating Pendulum model displays the dynamics of a mechanical oscillator in uniform circular motion. The mechanical oscillator is free to move in two directions. This 2-dimensional simulation displays all the dynamical features of the Foucault pendulum, except for the dependency of the Foucault pendulum precession on latitude. The simulation shows simultaneously the motion with...

Fourier Sine Series Model 1.0
Study the sine series expansion coefficients with this tool. The Fourier sine series model displays the sine series expansion coefficients of an arbitrary function on the interval.The Fourier Sine Analysis model computes the Fourier coefficients {am} using the discrete Fourier transformation algorithm. More efficient implementations that use the Fast Fourier Transformation (FFT) class in the OSP numerics library are available. Search the...

Shooting the Monkey 1.0 Java based classical shoot the monkey demonstration. Shooting the Monkey simulation allows the user to simulate the classical shoot the monkey demonstration. The user can change the initial velocity of the projectile, the positions and aim of the gun, and the position of the monkey.The simulation was created using the EasyJavaSimulations (Ejs) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the...

Falling Slinky Model 1.0
Slinky approximation made easy. Falling Slinky model approximates a slinky using twenty masses connected with light springs. The slinky is suspended from one end and released. Two actions will occur simultaneously when it is released hanging at rest from its equilibrium position - it will fall and it will collapse. What happens to the bottom when it begins its fall?1. The bottom end will move up initially.2. The bottom end will move down...

Double Pendulum Model 1.0
Analyze the double pendulum motion with this application. The Double Pendulum model displays the motion of a double pendulum and its Poincare map. A double pendulum is a pendulum with another pendulum attached to its end and the state of this dynamical system is specified by two angles and two angular velocities. Because there is no fiction, the double pendulum is an example of a Hamiltonian system and energy is conserved.?This EJS model...

Electric Generator Model 1.0
Study electromagnetic induction with this simulation. Electric Generator Model shows a simple electric generator made from a conducting loop rotating in a uniform magnetic field and connected to an ammeter. The model shows a plot of the magnetic flux and induced current. If Ejs is installed, right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item allows for editing of the model.Requirements:* Java

Faraday Disk Dynamo Model 1.0
Analyze magnetic field with this tool. The EJS Faraday Disk Dynamo shows a conducting disk that rotates in a magnetic field.
