## How Does a Skydiver Change Their Air Resistance?
As a skydiver falls through the air, they experience air resistance, which is a force that opposes their motion. The amount of air resistance they experience depends on a number of factors, including their speed, their surface area, and the density of the air.
Speed
The faster a skydiver falls, the more air resistance they experience. This is because the air has to move out of the way more quickly, which creates more drag.
Surface Area
The more surface area a skydiver has, the more air resistance they experience. This is because there is more air to push against. A skydiver with a large surface area, such as a wingsuit flyer, will experience more air resistance than a skydiver with a small surface area, such as a base jumper.
Density of the Air
The density of the air also affects the amount of air resistance a skydiver experiences. Air resistance is greater in denser air, such as at sea level, than it is in less dense air, such as at high altitudes.
How Skydivers Change Their Air Resistance
Skydivers can change their air resistance by changing their speed, their surface area, or the density of the air.
Speed
Skydivers can change their speed by adjusting their body position. A skydiver who is falling in a head-down position will experience more air resistance than a skydiver who is falling in a feet-down position.
Surface Area
Skydivers can change their surface area by using different types of equipment. A skydiver who is wearing a wingsuit will have a larger surface area than a skydiver who is not wearing a wingsuit.
Density of the Air
Skydivers cannot change the density of the air, but they can take advantage of changes in air density. For example, a skydiver who is jumping from a high altitude will experience less air resistance than a skydiver who is jumping from a low altitude.
Conclusion
Air resistance is a force that opposes the motion of a skydiver as they fall through the air. The amount of air resistance a skydiver experiences depends on their speed, their surface area, and the density of the air. Skydivers can change their air resistance by changing their speed, their surface area, or the density of the air.
