Free Fall Calculator (from Distance)

Find the fall time and impact speed of a free fall from the drop distance, using g=9.80665 m/s² and ignoring air resistance.

Input

For a free fall with zero initial speed and no air resistance, find the fall time and impact speed from the drop distance.

Gravity is set to g=9.80665 m/s².

Result

Falling freely through 10 m

Fall time

1.428087 s

Startd = 10 m14.004749 m/s

Impact speed

14.004749 m/s

Impact speed (km/h)

50.417097 km/h

Gravity

9.80665 m/s²

Fall time t=sqrt(2d/g) and impact speed v=sqrt(2gd)=gt. Theoretical values with standard gravity g=9.80665 m/s² and no air resistance.

How it works

  • Models a free fall with zero initial speed and no air resistance.
  • Fall time is computed as t=sqrt(2d/g).
  • Impact speed is v=sqrt(2gd) (equal to gt), shown in m/s and km/h.
  • Standard gravity g=9.80665 m/s² is used.
  • Real falls are slower because of air resistance.
