Distance d travelled by an object falling for time t	Time t taken for an object to fall distance d	Instantaneous velocity vi of a falling object after elapsed time t	Instantaneous velocity vi of a falling object that has travelled distance d

Values are ideal without air resistance.
An example with air resistance is given (human real) for a skydiver with closed parachute,
using the terminal velocity of 195 km/h (~54 m/s).
