Springing Oddissey Gravitational attraction

This animation is caused by the gravitational attraction between two objects. The closer the objects are, the stronger their acceleration towards each other.

A slightly different iteration of the animation with audio can be seen here.

The springing code snippet (simplified)

      private function spring(ballA:Ball, ballB:Ball):void{
          var dx:Number = ballB.x - ballA.x;
          var dy:Number = ballB.y - ballA.y;
          var dist:Number = Math.sqrt(dx * dx + dy * dy);

          var ax:Number = dx * springAmount;
          var ay:Number = dy * springAmount;

          ballA.vx += ax / ballA.mass;
          ballA.vy += ay / ballA.mass;
          ballB.vx -= ax / ballB.mass;
          ballB.vy -= ay / ballB.mass;
          }
      }
