Physics in DnD[edit]

These equations are straight out of my AP physics class most of these equations use the metric system please excuse and misspellings english is not my forte

 D=(Vi*t)+(.5*a*t^2)              D = distance                      m = mass
 D=(Vf*t)-(2*a*t^2)              Vf = velocity final               ΔV = the change in velocity
 D=.5(Vf+Vi)*t                   Vi = velocity initial             Δt = the change in time
 Vf=Vi+(a*t)                      a = acceleration
 Vf^2=Vi^2+(.5*a*d)               t = time
 F=ma                             F = force 
 a=(ΔV/Δt)

Falling[edit]

starting with no speed Acceleration due to gravity = 32 feet/second

 round 1                                                                          Force of hitting the ground
 Distance travelled                Speed                                          (assuming it takes .25 seconds to come to rest and the average 
                                                                                   medium character is 160lbs or 70 kilograms )
 D=(Vi*t)+(.5*a*t^2)               Vf=Vi+(a*t)                                    F=ma                a=(ΔV/Δt)
 D=(0*6)+(.5*32*6^2)               Vf=0+(32*6)                                    F=70*768            a=192/.25
 D=(0)+(576)                       Vf= 192 feet/second = 130.9 miles/hour         F=53,760 newtons     a=768 meters/second^2
 D=576 feet                                                                         1 newton = .22481 pounds of force
                                                                                53,760/.22481 = 239,135.27 pounds of force
 round 2
 D=(192*6)+(.5*32*6^2)             Vf=192+(32*6)
 D=(1152)+(576)                    Vf= 384 feet/second = 261.8 mph
 D=1,728 feet

Note: the average human dies after a 50-60 foot fall
