Fall Time Formula Guide

t = √(2h/g)
t
Time to fall (seconds)
h
Height (meters)
g
Gravity (9.81 m/s² on Earth)
Impact Velocity
v = g × t (m/s)

Safety Guidelines:

  • < 5 m/s → Low Risk
  • 5 - 10 m/s → Moderate Risk
  • 10 - 20 m/s → High Risk
  • > 20 m/s → Severe Risk
Any positive values allowed. No air resistance considered. Fall protection required for heights above 2 meters in many workplaces.
