[Rq-rules] Re: Knockback and falling damage.

Not this again! The bugaboo of impact damage has haunted gaming boards for decades. And trust me, even guys with physics degrees cannot agree on what actually causes impact damage. Is it velocity, elasticity of collision, kinetic energy, blah blah blah.
 
After observing a great many of these debates, it is my conclusion that it's simply not worth the effort to try to have a realistic impact mechanism. Just use the simplest table that seems somewhat believable and don't worry about it.

More silliness with maths.
 
To calculate the final velocity (v) when falling a certain distance (s):
 
Using v^2 = u^2 + 2as, we have
v^2 = 0 + 20s (u=0m a=10)
v=sqrt (20s)
 
With the previously-calculated formulae for horizontal distance/velocity, we can work out the horizontal distances travelled for a certain starting height. All distances are in metres, all velocities in m/s.
 
Plugging these into an Excel spreadsheet gives the following handy table:
 
                                        Horizontal Horizontal
Distance Equivalent           Distance   Distance
Travelled Velocity Damage (0.44)        (0.6)

So, you are whacked by a giant on a flat trajectory, 1m from the ground and travel 10m. This does 8D6 damage. The giant hits you a little bit higher for the same distance and the wall you hit does 5D6 damage.
 
It's inadvisable to be hit for more than 20m or so, as it may damage your health.
 
See what madness maths leads you into? It's best to forget about it and use a simple, incorrect but reasonable-looking table.
