Gravitorium Pro 1.0.15 (Shareware, $17)

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

MaterialWorlds Simulations 1.5 (Shareware, $19.95)

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 (free worksheets provided for pendulum, Newtons cradle, terminal velocity and Galileos balls - as dropped from the Leaning Tower of Pisa) - latest release includes machines ( pendulum clock and siege engines) bridge, crash and ideal gas simulations and experiments. With real-time visualisation of forces and velocities (as arrows on each object as they interact or are pulled around with the mouse) and scrolling graphs recording what happens, MaterialWorlds gives a real feel for how the physical world works.

Newton's Aquarium 1.0b2 (Commercial, $26.00)

Newton's Aquarium is a solar system construction set that allows students to create and explore situations involving any number of stars, planets, moons and asteroids. This software takes an interactive, visual approach to physics. Newton's Aquarium will help students develop an intuition for orbital mechanics. Students will gain a better understanding of the physics behind the images. By creating and exploring their own solar systems with Newton's Aquarium, students encounter the core concepts in classical physics.

Newton's Law (Windows) 1.0 (Shareware, $11.95)

In Newton's Law, players drop black holes and disturb the path of a traveling planetoid, with the goal of pulling it into a stable orbit. Moving the black hole

Orbit Xplorer 2.0 (Shareware, $25.00)

Educational orbit and gravitation simulator for high school, college and beginning university physics and astronomy. Input mass, radius, coordinates and velocity components of 2 to 10 bodies manually or by dragging and dropping predefined bodies. Then watch how the orbits evolve under the mutual gravitaional attractions. Save and print the simulation.
