How to use the Free Fall with Air Resistance Calculator
- Fill in the values you know. Fields already contain typical example values that you can overwrite.
- Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
- Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
- A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.
If a value is missing or does not make sense, the field shows a short message explaining what to fix.
Formulas used
This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:
air_resistance_coefficient = medium_density × cross_section / 2 × drag_coefficient
terminal_velocity = sqrt(mass×gravity/air_resistance_coefficient)
fall_time = sqrt(mass/(gravity×air_resistance_coefficient)) × if_else(altitude×air_resistance_coefficient/mass < 50, acosh(exp(altitude×air_resistance_coefficient/mass)), acosh(5e21))
drag_force = air_resistance_coefficient × drag_velocity^2
maximum_velocity = sqrt(mass×gravity/air_resistance_coefficient) × tanh(fall_time×sqrt(gravity×air_resistance_coefficient/mass))

Frequently asked questions
What inputs are needed for the calculator?
The primary inputs for the Free Fall with Air Resistance Calculator typically include the mass of the object, its initial height, the drag coefficient, the cross-sectional area, and the acceleration due to gravity (usually 9.81 m/s²). You may also have the option to specify the density of the air.
Can I use the calculator for any type of object?
Yes, the calculator can be used for various types of objects, as long as you provide accurate parameters such as mass, shape, and size. Common examples include balls, skydivers, and projectiles. However, keep in mind that the drag coefficient can vary based on the object’s shape.
What is terminal velocity?
Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the air prevents further acceleration. At this point, the net force acting on the object is zero, meaning the force due to gravity is balanced by the drag force.
