HighMoon is a game similar to "Artillery" or "Worms" -- but it takes place in the universe. There is a planet system between two flying saucers. The gravitational fields of the planets and moons change inevitably each ballistic curve. In HighMoon is not easy to eliminate an enemy. If you miss... Platforms: *nix

Circuit Aid contains a resistor circuit analysis tool that can build up to an 18 resistor series-parallel circuit. This tool will display voltage, amperage, and power used by every resistor in the circuit by means of mesh analysis. In addition, the program also contains a resistor color band... Platforms: Mac

TriVectus Gravity is a chaotic, scientifically inspired screen saver created in OpenGL. At its heart is a collection of planets that exist in a miniature universe. Each planet has mass and velocity, and is affected by gravitational forces from all of the other planets. Eventually, the planets... Platforms: Mac

TriVectus Planets is a screen saver that displays and animates various planetary systems. In addition, you'll see exploding planets, asteroid swarms, rouge asteroids, and nuclear war, among other things. Watch a planet's moon spiral into space after the planet explodes, or see how a rouge... Platforms: Mac

Halley is a handy application that allows you to access and get various informations about comets. Works with the comets database, containing Keplerian orbital elements, non-gravitational and physical parameters of the comet, and other data. The database is updated in case the new data become... Platforms: Windows, Windows Vista, 7

An award winning computer game built to help anyone trying to learn or brush up on their multiplication skills. Work your way through the solar system, saving outposts on planets and space stations from gravitational anomalies. The game includes: - 11 levels - Real information about the Moon,... Platforms: Mac

For a quick, fun way to reinforce your multiplication facts, you can't beat Math-teroid. Gravitational anomalies have caused asteroids to be attracted to the space station. It's your responsibility to keep the station safe as long as possible. Click on an asteroid to get it's incoming... Platforms: Mac

Visualization tool for the N-body problem. The first program of its kind for Mac OS X, it has an intuitive interface, beautiful graphics and an accurate and fast core physics engine. Cavendish is named for Henry Cavendish (1731 - 1810) who used a torsion balance to make the first accurate... Platforms: Mac

An easy-to-use program that solves the n-body problem. It accurately simulates gravitational interactions between an arbitrary number of objects. (For clarity, dynamics are restricted to the plane). You can create systems in Cavendish's intuitive graphical interface or write systems in... Platforms: Mac

The Flying Dogs Screen Saver shows dogs orbiting round the center of the desktop. They obey gravitational attraction according to physical laws, so their behavior is chaotic and never repeats. There are options to clear the desktop, leave trails, use your own dog images and more. Platforms: Windows

Phi = keplerSTM(x0,dt,mu) will return the state transition matrix Phi for a set of objects described by initial positions and velocities (x0) with gravitational parameters mu, propogated along Keplerian orbits for time dt. The positions and velocities at time dt is then given by Phi*x0. x0 must... Platforms: Matlab

This spacecraft begins in a GTO and spirals out of Earth's SOI, then orbits around the sun and spirals in to Mars. This model uses ODE23 to integrate a 4-body gravitational model including a forcing function. The engine has an Isp of 3000 sec and a thrust of 200 mN. This was basically a code I...

Magnetic levitation is defined as equilibrium of a body without any contact in the solid surface by the result of magnetic field. Trains working based on this technology is called as maglev trains. Recently, our focuses are to making accurate and high speed travelling system so all attentions... Platforms: Matlab

The NVIDIA GPU Computing SDK provides hundreds of code samples, white papers, to help you get started on the path of writing software with CUDA C/C++, OpenCL or DirectCompute. The SDK code samples covers a wide range of applications and techniques, including: Simple techniques demonstrating... Platforms: Mac

The Rocking Semicircular Hoop model shows the dynamics of a simple object rocking without slipping on a horizontal surface. It is a supplemental simulation for an article by Leaf Turner and Ari Turner "Asymmetric rolling bodies and the phantom torque" in the Am. J. Phys. 78, 905 (2010). The... Platforms: Mac

This interactive simulation shows a stone block lying at rest on an inclined plane. Initially, the component of gravity along the plane surface is exceeded by the force of static friction. The slope of the ramp can be increased or decreased, allowing students to see the exact point when the... Platforms: Mac

Gravitation is an interactive physical simulation program. It allows you to study the movement of celestial bodies in their mutual gravitational field. It can for example be used to illustrate Kepler's laws of planetary motion or to create a simulation of the solar system. Gravitation is written... Platforms: *nix
