GravOtron is a Puzzle game where the player controls the pull of gravity. While having control over the directional pull of gravity, the player must navigate 4 Orbs to each other until all 4 Orbs are one; doing so before their time or turns run out. With many options to customize your gameplay session, as well as randomized levels (allowing a combination of 5,000 different level setups!), the newness and replay value never ends with GravOtron!

Gravity is a fascinating four-in-row game.
The goal of the game is to arrange four stone in a row.
You can put a piece on any cell. The gravitation will then pull the stone to the closest edge on the board. If equally close to two edges stone will be pulled diagonally.
xGravity supports database of game, has full color graphics and more...

Live interactive physics simulations let you explore the Solar System (orbits, seasons, gravity, tides, satellites and comets), play snooker (on a full size table) and experiment with Laws of Motion simulations. Now with machines ( pendulum clock and siege engines) bridge, crash and ideal gas simulations and experiments.

Do you know lows of gravity discovered by Galileo, Newton and other great physics ?.
If your answer is "Yes" then you can put the ball exactly in center of the target.
This is goal of the game.

To push the ball tap on it and slide the stylus to left. This slide will define force applied on ball.

MBSS Gravity Wells is the quintessential celebration of color, motion and mathematics as particles fill the screen in brilliant patterns as influenced by wandering gravity wells. Setup properties of the emitters and attractors along with the Hue Cone for particle coloring. Gravity wells are depicted using real-time 3D particle animation where many of the attributes can be configured from the Properties dialog. A variety of themes are included.

MBSS All Products includes: Light, Fireworks, Starfields and Gravity Wells. Each product provides amazing 3D real-time particle animation. Properties can be customized or cycle through an effective variety of themes. Fireworks includes stereo sound effects. Create Video files from the animation. Blend the animation effects with the Windows Desktop Wallpaper. Capture the display to the Windows Clipboard, Image files or Windows Desktop.

Physics Cheat Sheet DEMO is an interactive physics package that helps students solve and visualize numerous physics equations. By checking their homework problems with Physics Cheat Sheet DEMO, students will better develop the mathematical thinking skills needed to succeed in physics. Physics Cheat Sheet DEMO was designed for use in high school and college physics courses.

How fast does gravity travel? What is it about mass that causes the force to exist? Is gravity a particle? Gravity has raised many unanswered questions throughout the ages. It is a force that we are all accustomed to in our daily lives - and yet how much of the subject do we really understand? This gravity calculating tool is designed to help determine the force that should exist between two objects containing mass.

The xOffice for PALM is collection of classic and non-classic board games for your PALM device.
You can purchase all these games separately. But it will be cost you a lot.
Much better purchase them all only for $30.00 !

Gravit is a gravity simulator which runs under Linux, Windows and Mac OS X. It's released under the GNU General Public License which makes it free. It uses Newtonian physics using the Barnes-Hut N-body algorithm. Although the main goal of Gravit is to be as accurate as possible, it also creates beautiful looking gravity patterns.

MBSS Starfields offers the ability to define starfields, nebulas, northern lights, comets, plasma clouds, neon spark ribbons and more. Setup properties of the stars and effect patterns along with the Hue Cone for particle coloring. Starfields are depicted using real-time 3D particle animation where many of the attributes can be configured from the Properties dialog. Field-level Online Help is included as well as an effective variety of Themes.
