1000X Kick Force Simulator (2D)

2D impulse-momentum model of an amplified kick: drag leg mass, swing speed and contact time and watch peak impact force update in real time next to a side-view leg-swing animation with an impact flash.

This is the 2D companion to the 3D "1000× kick force" biomechanics laboratory, built on the same impulse-momentum physics but exposed through the real inputs that actually set impact force — leg mass, swing speed and contact time — instead of a single force multiplier. Adjust the three sliders to see how each one reshapes the peak force delivered on impact, watch the side-view leg-swing animation track your swing speed, and trigger a kick to see the impact flash and resulting peak/average force and kinetic energy.

⚙ Under the hood

2D impulse-momentum model of an amplified kick, deriving peak impact force from leg mass, swing speed and contact time next to a side-view leg-swing animation with an impact flash.
