The Ejs Wave Representations model displays two representations of a sinusoidal wave on a string. One shows a movie of the wave traveling along a string - you can think of this representation as a sequence of photographs. The second representation is a plot of the displacement as a function of...

The EJS Molecular Dynamics Demonstration 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...

The Ejs Duffing Phase model computes the solutions to the non-linear Duffing equation, which reads, x'' + 2?zN*x' - x (1 - x2) = f cos(?Ya* t), where each prime denotes a time derivative. The simulation displays the evolution of a group of oscillators with similar initial parameters on a phase...

The Ejs Falling Rod Leaning on a Wall model displays the dynamics of a falling rod that is initially leaning against a vertical wall. The rod is dropped from rest while its end points are in contact with a vertical wall and a horizontal table. Friction is neglected. Fall times and the trajectory...

The EJS Faraday Disk Dynamo shows a conducting disk that rotates in a magnetic field. This produces a current (homopolar generator) and for certain configurations, it is a self-exciting dynamo. A self-exciting dynamo is the mechanical analog of a proposed mechanism to produce the earth and sun's...

The Ejs Free Particle Wavepacket model displays the time evolution of a free (V = 0 everywhere) initial Gaussian wave packet in position and momentum space. The default wave functions have = 0 and = 0, respectively. The initial width of the position-space wavepacket can be changed with the...


Platforms: Mac

The Ejs Hard Disk Collision model displays a two-dimensional collision between two hard disks. The two disks have the same mass and only one mass is moving at the beginning of the simulation. The impact of the collision is offset by the impact parameter, b, which can be changed. The...


Platforms: Mac

The Ejs Free Fall Cartesian model displays the dynamics of a ball dropped near the surface of Earth onto a platform. The initial conditions for the ball are an initial positive velocity in the x direction and zero initial velocity in the y direction. The coefficient of restitution for the ball's...
