Force vs. Momentum

A punch delivers impulse: force multiplied by the time it acts. A fast jab has a short contact time, so it can hit with high peak force yet transfer relatively little momentum.

A typical professional punch lands with around 1,000 newtons of peak force, and the hardest heavyweight blows reach several thousand. The difference is not just strength — it is the kinetic chain that links legs, hips, torso, and fist into one coordinated strike.
