[edit] G
Gravity in the sodaplay applet. Every step, vertical velocity is incremented by the gravity, or decremented if reverse gravity is on.
It is between 0 and 4 in the xml file.
[edit] F
The friction coefficient. Each step, all mass speeds are multiplied by (1-f).
Its value is between 0 and 1.
[edit] K
Hooke's constant in the applet. It determines the "springiness" of springs. The formula for springs, as approximated by Gizmo is:
For mass 1:
xv2 = xv1 + n * (x1 − x2)
yv2 = yv1 + n * (y1 − y2)
For mass 2:
xv2 = xv1 − n * (x1 − x2)
yv2 = yv1 − n * (y1 − y2)
