Software to simulate how objects move and interact under the force of gravity.
AstroGrav is a software application that allows you to study how astronomical objects move and interact under the force of gravity. AstroGrav features superb interactive 3D graphics which allow you to move around within an astronomical system that you are viewing, while 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, and these enable 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, and provide you with an almost endless scope for experimentation and investigation.AstroGrav is an astronomy software program that can be used for simulating the way astronomical objects shift and interact when affected by the force of gravity.AstroGrav is very accurate, dynamically calculates orbits as a system evolves, deals correctly with object collisions, and can cope simultaneously with objects on many different timescales. For a system containing a small number of particles, you can watch the system evolve as in a movie. For a system containing a larger number of particles, the calculations will take longer, and you may have to wait to see the next state of the system. Here are some key features of \"AstroGrav\":
· Basic concepts of mass, position, velocity, acceleration, force, momentum, and energy.
· Kepler\'s Laws of Planetary Motion and Newton\'s Law of 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.
· 600 MHz Intel Pentium III processor or equivalent
· 128 MB RAM
· 50 MB disk space
· 14 days trial
· Nag screen What\'s New in This Release: [ read full changelog ]
· Changed the way that Units and Notes windows are displayed, so that they can be left open while interacting with other parts of the user interface.
· Added the asteroid 2010 SO16 to the Earth\'s Quasi-Moons sample simulation.
· Added the Earth Trojan sample simulation to show the asteroid 2010 TK7, which was recently discovered to occupy a Trojan orbit with respect to the Earth.
· Added the Units window to many of the sample simulations.
· Corrected a fault that could cause the significant digits of position and speed quantities to get reduced to 4.
· Corrected a fault that caused a window with a tool palette to disappear when another application\'s window was clicked.
· Various minor bug fixes and improvements.
