Motion Of Projectiles

This interactive simulation shows an airplane flying at constant horizontal velocity preparing to drop relief supplies to a small island. As captain of the plane, the student must first calculate the release point for dropping the package. As the simulation runs, press the red "+" button at the...

The EJS 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 Ejs Damped Driven Harmonic Oscillator Phasor model displays the motion of damped driven harmonic oscillator. The resulting differential equation can be extended into the complex plane, and the resulting complex solution is displayed with the real part of this solution being the position of...

The Astronomical Parallax 2D Model illustrates the phenomenon of parallax in astronomy. Parallax is the apparent displacement of an object relative to the background that is caused by the motion of the observer (rather than the motion of the object itself, or of the background). This simulation...

So, what is a linetester for? When animators working in the conventional 2D drawn animation method first start drawing an animated scene they tend to work in a rough, sketchy style which helps them get a feeling for the motion of characters. These rough drawings are the basis of `linetests` using...
