Hi. I need to do a type of F=M*A equation to calculate damage for my character (or perhaps something a little simpler) and I'm having a bit of trouble with it. This is what I have working:

((Building.Physics.Mass * (abs(Building.Physics.VelocityX) +abs(Building.Physics.VelocityY))) * 0.008)

This works pretty well, except that if you are standing on something that happens to be moving fast (like driving a car or riding a skateboard), it will kill you...

Can anyone help me out with a better equation?
