Physics of Skydiving

Power of gravity at work ... God is obviously skydiving for us. After all, he produced gravity. So what is the power of Skydiver? Of course, there is one obvious thing. That is the gravity of the earth. Even if the parachute and the earth are not in direct contact, this force acts on everything on the earth and joins the parachute. This type of force is also called noncontact force when exerting force on each other even if two objects are not in contact.

In Newtonian physics, free fall is defined as the movement of an object, gravity is the only force acting on it. Through this definition, skydivers will never be free even before they develop parachutes. Skydivers can pull toward the earth by gravity, but they are also influenced by air resistance, the force opposing the downward movement. Therefore, it does not conform to the strict definition of free fall. So, what do you want about free fall? According to the definition of Newton, the moon itself is in free falling state! It is because the gravity of the earth is the only force acting on the moon. This precise definition is not a true falling device, but I think that it is not realistic to install the device in space or to assemble a huge vacuum cleaner for each device. The equipment of Head Rush is the most authentic free fall in the adventure park on the earth.

A few years ago, I was involved in a very cool video project. The project included Skydiver, which jumps off an airplane and develops the slopes after a free fall period. Ordinary everyday skydiving, is not it? Or the sky diver falls to the ground until his parachute suddenly flames up. A few seconds later he cut out the crisp parachute debris and placed the second slide to safely get down to the ground. The current block chain industry and enthusiastic fans of ICO remind me of this project.

1 Skydiving I do not know where the boundary between skydiving and skydiving is. I guess you've spent a lot of time on the road before opening the slide, which is why I like skydiving more than simple skydiving. I can not do it again, and I can not do it at least many times. So, if you stop using a piece of cloth just jumping down from a fatal height, please take time to enjoy the scenery and enter the road of somersault. For the same reason, I can not see the bungee's focus.
