## Falling Force Formula

The following equation is used to calculate the .

Ff = GF – AF

- Where Ff is the net force acting on a free-falling object (N)
- GF is the gravitational force = mass *9.81m/s^2
- AF is the force of air resistance (N)

To calculate the falling force, subtract the air resistance force from the gravitational force.

## What is a Falling Force?

Definition:

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.

## How to Calculate Falling Force?

Example Problem:

The following example outlines the steps and information needed to calculate Falling Force.

First, determine the gravitational force. This is calculated by multiplying the mass by the acceleration due to gravity, which in this case, is 50N.

Next, determine the force of air resistance. At it’s current speed, air resistance is equal to 25 N.

Finally, calculate the falling force using the formula above:

Ff = GF – AF

Ff = 50 – 25

Ff = 25 N
