Like a car hitting a concrete wall. The target cannot accelerate away, forcing energy to dissipate internally. High peak force causes tissue failure and shockwaves. Ideal for knockouts.

Like a car with crumple zones. Extended contact allows the target to accelerate away, converting energy to displacement. Lower peak force reduces internal trauma. Ideal for creating distance.

The Physics Behind It

Impulse-Momentum Theorem

J = F·Δt = Δp

For the same momentum change (Δp), force (F) is inversely proportional to contact time (Δt). Halving the contact time doubles the force.

Viscoelastic Response

Human tissue behaves differently at different loading rates. At high rates (snap), tissues become brittle and fail. At low rates (push), tissues are compliant and absorb energy.

Jerk & Knockouts

Jerk (rate of change of acceleration) is maximized in snap strikes. High jerk causes the brain to shear against the skull, leading to knockouts.
