sport.ground-reaction-force Calculator
Calculates the ground reaction force during jumping or landing from body weight and the vertical acceleration factor, critical for biomechanics analysis and sports injury prevention. Landing forces of 5–8× body weight are common in sports like basketball and volleyball.
Inputs
Body Mass Kg
Total mass of the body. Used with height to calculate BMI and estimate lean mass.
Peak Grf Bw
Reference formula or conversion factor shown for context.
Contact Time Ms
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Step Frequency Hz
Cycles per second (Hz). Audible sound: 20 Hz – 20 kHz. Make sure units match what the formula expects.
Results
peak ground reaction force (N)
The force exerted by a support on a structure. Equal and opposite to the applied load at that point (Newton's Third Law).
peak force (× body weight)
The computed weight (gravitational force) or mass.
