Orbits

In just a few lab periods, your students can be masters of the universe! Orbits lets them create their own planetary systems - complete with asteroids, moons, satellites, and stars - to explore the parameters of orbital and gravitational motion. With this interactive tool at their fingertips, it won't take long to master the concepts of classical orbital mechanics.

Orbits simulates the motion of planets, rockets, and stars in a highly visual forum. This promotes an understanding of classical mechanics that can't be matched by manipulating algebraic or differential equations. Students can vary the force laws of nature and make two galaxies collide, or pass an "intruder star" through a solar system to capture a planet!

The program will calculate and plot the motion of up to seven bodies. Two of the bodies are heavy; that is, their gravitational field affects all other objects. The other five bodies are light and do not influence the motion of other objects. You can vary velocity, change the value of the gravitational constant, or shift to a different frame of reference while maintaining existing orbits. This allows for straightforward investigation of retrograde motion and Lagrange point stability. Orbits is also excellent for student projects! 64 pp.

System Requirements:
