Law of Gravitation
This exploriment lets you explore Newton's Universal Law of Gravitation and how it applies to launching of a satellite. It illustrates how gravity, velocity and elevation affect the interaction of a small satellite orbiting a massive body. This simulation puts a classic two-body problem in your hands, and lets you interactively vary velocities and elevations for a satellite orbiting a massive object. The parameters in your control can be seen to interact with the the force of gravity that the massive body constantly exerts on the satellite. This is a particular case of the classic two-body problem, where a comparatively weightless object (e.g., satellite) orbits a massive object (e.g., planet).
