Gravitational

Einstein's General Theory of Relativity demonstrates that a large mass can deform spacetime and bend the path of light. So, a very massive object, such as a cluster of galaxies can act as a gravitational lens. With this program, one can draw images to see the effect of gravitational Platforms: Windows

Gravitational search algorithm (GSA) is an optimization algorithm based on the law of gravity and mass interactions.This algorithm is based on the Newtonian gravity: "Every particle in the universe attracts every other particle with a force that is directly proportional to the product of their...

A new hybrid population-basedalgorithm (PSOGSA) is proposed with the combination ofParticle Swarm Optimization (PSO) and Gravitational SearchAlgorithm (GSA). The main idea is to integrate the ability ofexploitation in PSO with the ability of exploration in GSA tosynthesize both algorithmsd-deOao... Platforms: Matlab

Two mass models and their gravitational quantities, gravitational potential,gravitational attraction and the gravity gradients are being compared. Basis are the formulas of Heck and Seitz 2006 which were also used for the tesseroids-1.0 software of Leonardo Uieda 2011. The Code derives the... Platforms: Matlab

KOPS project is a two-dimensional gravitational shootyerfriend game. This is a port from the DOS version. It features parallax scrolling with a full digital soundtrack and sound effects. A Pentium-class processor or better is recommended. You control your ship with five keys; thrust (move... Platforms: *nix

Visualize the gravitational force that two objects exert on each other. Change properties of the objects in order to see how it changes the gravity force. Platforms: Mac

The Ejs Newtonian Scattering model displays the gravitational scattering of a multiple masses incident on a target mass. The simulation displays the motion of the smaller. The number of particles and their initial spread, the gravitational constant, and the target mass's radius can be changed via... Platforms: Mac

GravitySaver is a light weight screensaver that expands upon the the iX Planets screensaver by adding a new dimension. What you see is an accurate 3-dimensional simulation of many bodies and their gravitational pull on each other. Collisions result in pulses being emitted from impact points. Platforms: Mac

Cavendish's screensaver module beautifully visualizes the gravitational forces shaping our universe, accurately predicting and drawing the paths of celestial bodies as their masses attract each other. The screensaver generates a 3D universe with randomly distributed bodies and then uses OpenGL to... Platforms: Mac

Gravity and Orbits is a a Java application designed to enable you to investigate the forces that affect planets. Move the sun, earth, moon and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between different heavenly bodies,...

Gravitation3D is a unique application that allows you to construct solar systems from scratch by adding gravitational bodies and configuring their starting properties. The application was designed to provide an intuitive understanding of the laws of gravity and it features an easy-to-use interface. Platforms: Windows

This demonstration shows a 3D scenario with 5 balls interacting by gravitational forces of attraction, bouncing and showing bursts when they collide. The user can shoot to the balls and change its trajectory. Supported controls: Keyboard, Mouse and Joystick. OpenGL features used: Blending,... Platforms: Windows

The prime purpose of Gravitorium is to let you play with ideas about gravity and gravitational systems. While it's not intended to be a highly accurate solar system simulator, at low speeds its accuracy is really pretty good. And, best of all, it lets you "play universe maker". Throw in a few...

Analysis and simulation of orbits in the circular-restricted three-body problem (CRTBP), where primary and secondary bodies move in circular orbits about the common center of mass, and effect of gravitational attraction of the smallest body are ignored. The applications described here are for... Platforms: Matlab

There are two components in this group.1. Hohmann Transfer Example: This simulation starts with a craft/satellite in low earth orbit. A Hohmann Transfer is initiated to a 'random' destination altitude. This includes the delta V to move to a higher orbit, and then circularize the orbit once the... Platforms: Matlab

Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time. View a Free Body Diagram of all the forces (including... Platforms: Mac
