This educational software simulates orbit and gravitation for high school, college, and beginning university physics and astronomy. It provides effortless creation, running, printing, and saving of simulations with 40 premade simulations and an activities page in html-format.

Once you have entered your objects, you can easily watch as the orbits evolve under the mutual gravitational attractions. Moreover, you can save and print the simulation to further study the data. This feature is particularly useful for conducting lab exercises in gravitational physics or verifying numerical answers to textbook problems.
This software comes with 40 pre-made simulations, ranging from introductory to advanced levels, each with its own activities page in HTML format. You can explore a variety of simulations, including elliptical satellite orbits, Kepler's laws, double star, geocentric and heliocentric world views, Lagrange points, gravity assist, Hohmann orbit, extrasolar planet, and inner solar system.
The Educational Orbit and Gravitation Simulator also use actual pictures of planets, and it allows you to plot orbits in a plane or in 3D. You can view time, distances, speeds, accelerations, energies, and acceleration vectors as they change, and adjust the simulation speed to fit your computer. This software also allows you to zoom in and change parameters during the simulation.
Lastly, you can run up to four simultaneous simulations, and the software comes with tutorial and context-sensitive help included. Overall, this software is an excellent tool for students who want to explore physics and astronomy in a fun and interactive way.
Version 3.00: Runs on high resolution displays. Nicer graphics. More simulatuons. Better stability on Windows 10. Can draw gravitational field and equipotential lines.
