The Free Fall (time) calculator compute the duration of time that an object will be in free fall based on the height and the.

Free Fall Duration (t): The calculator returns the time in seconds. However this can be automatically converted to compatible units via the pull-down menu.
is meant for the context of free fall, or constant acceleration downwards due to Earth's gravity without rest, ignoring air resistance. Here, t is the time it takes for the object in question to fall a given distance (Height) with it's acceleration of g (the acceleration at sea level due to gravity, roughly 9.8 m/s^2).
`t = sqrt( (2·h) / g)`
