Free Fall Calculator (from Velocity)

Find the fall time and fall distance from an impact velocity in free fall. Uses gravity g = 9.80665 m/s squared with t = v / g and d = v squared / (2g).

Input

Calculate the time to reach a given velocity in free fall and the distance fallen in that time.

Fall velocity v

Velocity unit

Gravity uses standard value g = 9.80665 m/s squared.

Result

Fall time t

3.059149

Fall distance d

45.88723

Velocity (m/s)

30 m/s

Velocity (km/h)

108 km/h

Velocity (mph)

67.108089 mph

Fall distance (km)

0.045887 km

In free fall the velocity is v = g t and the distance is d = v squared / (2g), ignoring air resistance with zero initial velocity.

How it works

Assumes ideal free fall with no air resistance and an initial velocity of zero.
Uses standard gravity g = 9.80665 m/s squared.
Fall time is t = v / g and fall distance is d = v squared / (2g).
The entered velocity is converted to m/s before calculation.
