Sorry, but that's wrong.
F=MA
Force = Mass x Acceleration
KE = 0.5MV^2
Kinetic Energy = One-Half x Mass x Velocity x Velocity
P = MV
Momentum = Mass x Velocity
SD = M/D^2/7000
Sectional Density = Mass (in grains) / Diameter (in inches) / Diameter (in inches) / 7000
DESIGN IS KING. The bullet design must be matched to the cartridge and target. Design cannot be captured by the basic physics equations and must be verified against a useful test protocol.
