find the total momentum of all the bodies.
Find total momentum
Begin NetLogo code:
let bodies objects with [my-mass > 0] set the-total-momentum-x sum [my-mass * xvelocity ] of bodies set the-total-momentum-y sum [my-mass * yvelocity ] of bodies if the-world-is-3-d? [ set the-total-momentum-z sum [my-mass * zvelocity ] of bodies ]
End NetLogo codeThis micro-behaviour finds the momentum of the entire solar system by summing the mass times the velocity of every body in the system.
