Velocity Verlet Algorithm

• Roundoff advantage of leapfrog, but better treatment of velocities

• Algorithm

• Implemented in stages

  • evaluate current force
  • compute r at new time
  • add current-force term to velocity (gives v at half-time step)
  • compute new force
  • add new-force term to velocity

• Also mathematically equivalent to Verlet algorithm (in giving values of r)
