Free fall with air resistance (time and velocity) Calculator

Calculates the free fall time and velocity with air resistance from the free fall distance.

The default value of the air resistance coefficient, k=0.24(kg/m), assumes the value in skydiving.

    Purpose of use
    To calculate how long it would take a person to fall 800m if they accidentally fell while hill-walking
    [9]  2020/04/23 11:09   Male / 60 years old level or over / An office worker / A public employee / Useful /
    Purpose of use
    Estimating the velocity of a single roll of wrapped toilet paper dropped from a C-130 at an altitude of 3000 feet. The airspeed of the aircraft is 250 knots.
    Comment/Request
    The airspeed of the aircraft is 250 knots. This equation doesn't allow for the calculation.

    Purpose of use
    Calculating terminal velocity of metal spheres.
    Comment/Request
    Cross-sectional area is not taken into account. I have to assume this is for an average adult human. You should say this in your preamble.
