AstroGrav allows you to study how astronomical objects move and interact under the force of gravity. It features superb interactive 3D graphics which allow you to move around within an astronomical system that you are viewing, watching how it evolves with the passage of time.
A wide variety of sample files are provided, including Solar System, space mission, and abstract systems, enabling you to experiment with AstroGrav without having to go to the trouble of entering your own data. The comprehensive editing facilities allow you to either create your own astronomical systems, or to modify existing ones.
Quickly get to grips with the following concepts:
• Basic concepts of mass, position, velocity, acceleration, force, momentum, and energy
• Kepler's Laws of Planetary Motion and Newton's Law of Universal Gravitation
• Many body systems and the n-body problem
• Orbits and Lagrange points
• Interchange of potential energy and kinetic energy in gravitational systems
• Projectiles and escape velocities
• Gravitational slingshots used in space missions
