Understand the physics principles of free fall

Fundamental principle of free fall: the law of gravity

It is impossible to talk about free fall without mentioning the law of gravity. Sir Isaac Newton described this law in his book, Principia Mathematica, which states that all objects in the universe are attracted to each other due to their mass. In simpler terms, this means that the Earth is constantly pulling us towards it.
The gravitational force depends on two factors:

  • The mass of objects: the more massive an object is, the greater the gravitational force.
  • The distance between objects: the further apart the objects are, the less intense the gravitational force.

In free fall, we see these forces in action. With nothing to support us, we fall toward Earth at a constantly accelerating rate until we reach terminal velocity.

Air resistance: a key factor not to be neglected

Although gravity is the main player in free fall, never underestimate air resistance. This physical phenomenon is the reason why not all objects fall at the same speed. This is because air produces a resisting force on objects moving through it, which slows their fall.
The strength of air resistance depends on several factors:

  • The size of the object: Larger or wider objects encounter greater resistance.
  • The shape of the object: Well-aerodynamic objects, such as an arrow, encounter less resistance than non-aerodynamic objects, such as a parachute.
  • The speed of the object: The faster an object moves, the greater the air resistance.

Terminal velocity: the ultimate limit of free fall

During free fall, a balance ultimately occurs between the force of gravity that pulls the object downward and the air resistance that opposes its fall. This is when the object stops accelerating and continues to fall at a constant speed. This speed is known as terminal velocity.
In Earth’s environment, the terminal velocity for a human is typically around 200 km/h in the extended position (a skydiver falling “flat”) and 320 km/h in the fetal position (a jumper at a full angle ).

Ensuring safety: understanding to better prepare

Free falling is an extreme activity that can present risks. Understanding the physics principles that govern this activity is essential to minimizing these risks. Before undertaking any activity of this type, ensure that you are properly trained and equipped. The right equipment, such as parachute or the jump suit can make a huge difference in your experience and safety.
Always be aware of your surroundings when engaging in any free fall activity. Any obstacle in your path could potentially increase air resistance and change your speed and fall path.
Understanding the physics of free fall can help you not only enjoy this exciting adventure even more, but also help you become a safer and more informed adventurer. Remember, safety first!

Learn emergency landing techniques without a parachute

Understanding the Physics of Free Fall

To learn how to emergency land without a parachute, it is important to understand what happens during a free fall. Your body undergoes force of gravity which pulls you towards the ground at a speed of up to 200 km/h. How to survive at such speed? This is where air resistance comes into play.

Air resistance: Unsuspected ally

During a free fall, the friction of air against your body creates resistance. This resistance can be increased by increasing the surface area of ​​your body that comes into contact with the air. This explains the classic position of parachutists: arms and legs apart, stomach down.

Choosing the Landing Place: Preparation and Adaptability

Avoiding hitting the ground at supersonic speed is only the first part of your challenge. It is equally crucial to choose the right place to land. Statistics show that environmental factors come into play in the survivability of a fall from a great height.

Snow or water? A crucial choice

In free fall, trying to land in the water might seem obvious. However, be aware that hitting water at a high speed is comparable to hitting concrete. Opt instead for the snow, which offers less resistance to speed.

Free Fall Rolling Technique

Once you have chosen a landing location, the roll technique can increase your chances of survival. It helps distribute the impact over a larger area of ​​the body, reducing the risk of serious injury to a specific part of the body.

Make the Body a “Shock Absorber”

To successfully roll, strike the ground with your feet first. Then, immediately spread your legs to prevent them from crushing against each other. Finally, get into the fetal position to protect vital organs and roll to dissipate the energy of the impact.
Despite everything, it is important to remember that these techniques in no way guarantee your survival. They only serve to increase your chances in the event of an extremely critical situation. So, during your extreme adventures, stay safe, stay informed and, above all, always keep your parachute at hand!

Adopt survival positions in mid-flight

Understand the importance of survival positions in mid-flight

When we think of aerial survival, the image that often comes to mind is that of an individual free-falling through the sky. However, surviving in mid-flight is not just about free fall. It also includes the ability to adopt the correct position during an emergency landing, or during turbulent flight on a small plane or helicopter.

Survival positions during a free fall

Adopting a good position during a free fall can not only extend your fall time, but also maximize your chances of surviving upon landing. Here are recommended positions:
Stitched position: This stance, also called “boom stance” or “missile stance”, allows you to fall toward the ground faster. It can be beneficial if you need to descend quickly, for example to avoid flying objects or to reach a safe area.
Horizontal position: Also called “parachute position”, it allows you to slow your descent and have limited control of your direction. This is the position generally adopted by skydivers to stabilize their fall.

Adopt the correct position in case of turbulence

When flying on a small plane or helicopter, turbulence can occur at any time. The goal in this case is to minimize the impact on your body. This usually involves curling up one’s body and protecting vital parts.
Start by leaning forward with your head between your knees while wrapping your arms around your legs. Your head should be as low as possible, without touching the surface in front of you.

Protecting your body during an emergency landing

Finally, the emergency landing is arguably the most critical moment when it comes to mid-flight survival. The goal is, once again, to protect your body as much as possible, especially your head and spine.
The position to adopt is similar to that of turbulence: lean forward with your head between your knees, and wrap your arms around your legs. However, be careful not to hit the surface in front of you directly with your head. Additionally, it is essential to do everything possible to relax upon impact to minimize the risk of injury.

Preparing for mid-flight survival is, without a doubt, a valuable skill for any adventurer. The survival positions discussed here are just a few examples of those you can adopt. As always, remember that each situation is unique and therefore requires a tailored response. Stay prepared, stay informed, and most importantly, stay safe.

Develop the spirit of survival when faced with a fall without a parachute

Understanding the Situation

When faced with a free fall without a parachute, understanding the situation is crucial. You have approximately 90 to 120 seconds before hitting the ground, depending on your body position. Use this time wisely, don’t panic. Remember that every decision counts.

Adopt the correct position

The position of your body is essential. Adopt a horizontal position, as if you were lying on your stomach. This maximizes your air resistance and slows your descent. This is a position that is often found during jumps. skydiving.

Choose your landing zone

Your chances of survival largely depend on your landing zone. Aim for wide open spaces – fields, lakes, snow-covered mountains. Avoid trees and buildings. These hard surfaces can cause serious injury.

Prepare for impact

Landing is the most critical phase. Focus on keeping your legs slightly bent, body leaning forward, and head tucked. This is a technique often used in skis and snowboard.

Soften the Shock

Roll on the ground to disperse the energy of the impact. It is a technique taught during skydiving sessions with Air Adventures. A rolling landing significantly reduces impact and the risk of major injuries.

Importance of training and mentality

If such a situation arises, having prior training can increase your chances of survival. Learning basic skydiving skills can be helpful. Even if you don’t have a parachute, these techniques can help you stay calm and make the right moves.

Maintain a positive mindset

Survival in such a situation does not only depend on the physical aspects, but also on your mind. Stay hopeful and focus on what you need to do to survive.
This guide may seem dramatic and extreme, but it highlights the importance of being prepared for any eventuality. Developing a survival mindset is not limited to falling without a parachute, these principles can be applied to other life situations. Focus, understanding, and maintaining a positive mindset are essential tools for survival, whatever challenges you may face.

The main thing to remember

  • Understand the situation
  • Adopt the correct position
  • Choosing your landing zone
  • Prepare for impact
  • Lessen the shock
  • Importance of training and mentality
  • Maintain a positive mindset

This is not an exact science, but general advice that has been shown to increase the chances of survival. Every situation is different and implementing these tips depends on the specific situation. However, never lose hope. The human spirit is incredibly resilient when faced with challenges, and by keeping calm and thinking logically, you give yourself the best chance of survival.
