## What is free fall?

In the world of physics, ‘free fall’ describes the motion of an object when it’s influenced solely by gravity, without any other forces at play. It’s important to note that this doesn’t always mean the motion is strictly downward. For example, even the Moon can be considered in a state of free fall as it’s primarily under the Earth’s gravitational influence.

However, in the context of our Free Fall with Air Resistance Calculator, we take a slightly more practical approach to ‘free fall.’ Here, we define it as any object moving towards the ground without external acceleration or deceleration. Take a skydiver or a parachutist descending to Earth, for instance – they fall into this category. In such situations, two forces are at work: gravity, which pulls them downward, and air resistance, which slows their descent.

So, whether you’re exploring physics or simply curious about the dynamics of free fall, our Free Fall with Air Resistance Calculator is here to help you understand and analyze the forces at play in everyday scenarios. Dive into the world of gravity and resistance with confidence!

## Air resistance formula

Air resistance, also known as aerodynamic drag, is a natural force that pushes back against any object falling freely through the air. The faster an object falls, the stronger this resistance becomes. We can measure this effect using a simple formula:

F = k × v²

In this equation, ‘v’ represents the object’s speed, and ‘k’ is the air resistance coefficient, which is measured in kilograms per meter.

Now, let’s break down how ‘k’ is calculated using this air resistance formula:

k = ρ × A × C / 2

- ρ: This symbolizes the density of the air the object is moving through. We assume standard air density at 15°C, which is 1.225 kg/m³. If your situation involves different conditions, our advanced settings allow you to adjust this value. We also offer a Stokes’ law calculator for objects moving through other substances like water or glycerine.
- A: This is the cross-sectional area of the falling object, essentially the area it presents to the air.
- C: The drag coefficient, a dimensionless number, depends on the object’s shape. For example, a cube will experience much more air resistance than a teardrop due to its higher drag coefficient.

By default, ‘k’ is set at 0.24 kg/m, ideal for skydivers. However, you can customize this value to fit your specific needs using our advanced settings. Just remember to clear the existing 0.24 value when entering a new one.

## Maximum vs. terminal velocity

Understanding Free Fall with Air Resistance: As an object falls, gravity pulls it down, causing a steady acceleration. But there’s more to the story – as the object gains speed, air resistance fights against it. Eventually, air resistance can equal gravity, stopping the acceleration. This moment is the object’s terminal velocity.

It’s worth mentioning that not every falling object reaches terminal velocity. Some hit the ground before that. That’s why our Free Fall with Air Resistance Calculator gives you a different answer – the maximum velocity before it stops. Explore this phenomenon with our tool today.

## How to calculate air resistance with Free Fall with Air Resistance Calculator?

Let’s dive into a real-life scenario involving a skydiver making their descent back to Earth. We want to figure out how long their fall will last, what their top speed will be, the critical terminal velocity, and the strength of the air resistance pushing against them when they reach their fastest.

First off, we need to know the skydiver’s weight. For our example, let’s say it’s 75 kilograms.

Next, pick a starting height for their plunge – for this exercise, we’ll go with 2000 meters.

You’ll also need to select an air resistance coefficient. Or if you’re feeling adventurous, you can compute it yourself (just remove the default value). But for now, we’ll stick with the default coefficient of 0.24 kg/m.

Now, enter these numbers into the Free Fall with Air Resistance Calculator. It’ll do the heavy lifting for you: a fall duration of 40 seconds, a terminal velocity of 55.4 m/s, and a max speed also at 55.4 m/s. Looks like our skydiver has hit that sweet terminal velocity mark!

Take this 55.4 m/s value and put it into the last part of the calculator to figure out the drag force acting on our skydiver. The calculator will do the math for you:

F = k × v²

F = 0.24 × 55.4²

F = 736.6 N

Now, compare this result with what you’d get from a regular free-fall calculator. Can you spot the difference?

And for those who’ve stuck around to read this far, we’ve got a special treat for you – a captivating video demonstrating one of the most iconic free fall experiments.

Plus, here’s our very own Alvaro breaking down the key distinctions between this Free Fall with Air Resistance Calculator and the standard free-fall calculator. Enjoy exploring the world of physics in action!
