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.

F

The friction coefficient. Each step, all mass speeds are multiplied by (1-f).

Its value is between 0 and 1.

K

Hooke's constant in the applet. It determines the "springiness" of springs. The formula for springs, as approximated by Gizmo is: 96254b97b50b39f8d6a6c1f675933ff8.png

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)
