Falling Force Calculator

Formula

The formula to calculate the Falling Force is:

$F_f = GF - AF$

Where:

$F_f$ is the net force acting on a free-falling object (N)
$GF$ is the gravitational force = $\text{mass} \times 9.81 \, \text{m/s}^2$
$AF$ is the force of air resistance (N)

What is a Falling Force?

A Falling Force is when the combined acceleration of gravity and the inertial reaction of an object's mass result in a net downward acceleration. In other words, a falling force is a net force acting on an object that is falling from a certain point.

Example Calculation 1

Let's assume the following values:

Mass of the Object = 10 kg
Force of Air Resistance = 20 N

Using the formula:

$GF = 10 \times 9.81 = 98.1 \, \text{N}$
$F_f = 98.1 - 20 = 78.1 \, \text{N}$

The net falling force is 78.1 N.

Example Calculation 2

Let's assume the following values:

Mass of the Object = 15 kg
Force of Air Resistance = 30 N

Using the formula:

$GF = 15 \times 9.81 = 147.15 \, \text{N}$
$F_f = 147.15 - 30 = 117.15 \, \text{N}$

The net falling force is 117.15 N.
