Developer website: Benjamin Blonder

Cavendish Education is an easy-to-use gravity simulator that solves the n-body problem. It accurately models gravitational interactions between an arbitrary number of objects. (For clarity, dynamics are restricted to the plane). You can create systems in Cavendish's intuitive graphical interface or write systems in Cavendish's scripting language - all saved files are plaintext format.

Features:
  • Guaranteed energy and momentum conservation - Cavendish uses a fourth-order Runge-Kutta algorithm with adaptive time-stepping.
  • Multiple restore points - restore a system to any past configuration!
  • Velocity/acceleration vector rendering - you can see the forces on an object.
  • Trace line rendering - objects can leave a trail behind them to visualize orbits. Inelastic collisions between objects - objects can be point masses or have finite radius.
  • Variable simulation speed - run quickly to complete an orbit or slow down to focus on a close approach.
  • Automatic view control - follow an object or the system's center of mass.
