## What is the Average Speed of a Skydiver?
Skydiving is an exhilarating sport that involves leaping from an aircraft and freefalling towards the ground. The speed at which a skydiver falls depends on several factors, including their body position, the altitude at which they jump, and the air density.
### Factors Influencing Skydiving Speed
#### Body Position
The position of a skydiver’s body significantly impacts their speed. When a skydiver is in a spread-eagle position with their arms and legs extended, they experience the most air resistance and fall at a slower speed. Conversely, when they are in a streamlined head-down position, they encounter less air resistance and fall much faster.
#### Altitude
The altitude from which a skydiver jumps also affects their speed. At higher altitudes, the air is less dense, providing less resistance and allowing skydivers to achieve higher speeds. As they descend, the air becomes denser, increasing the resistance and slowing them down.
#### Air Density
Air density is another crucial factor that influences skydiving speed. Cold air is denser than warm air, meaning that skydivers will fall slower on colder days. Similarly, skydivers jumping at higher altitudes encounter less dense air and can reach greater speeds.
### Average Skydiving Speed
The average speed of a skydiver varies depending on the factors mentioned above. However, in general, experienced skydivers typically fall at speeds ranging from:
90-120 mph (145-193 km/h) in the spread-eagle position
120-180 mph (193-289 km/h) in the head-down position
### Terminal Velocity
As skydivers freefall, they approach a constant speed known as terminal velocity. Terminal velocity is the speed at which the force of gravity acting on the skydiver is equal to the force of air resistance acting in the opposite direction. For experienced skydivers in a head-down position, terminal velocity is typically around 120 mph (193 km/h).
### Factors Affecting Terminal Velocity
Several factors can affect terminal velocity, including:
Body Mass: Heavier individuals have a greater force of gravity acting on them and reach terminal velocity faster.
Surface Area: Skydivers with larger surface areas, such as those using a wingsuit, experience more air resistance and have a lower terminal velocity.
Air Density: As mentioned earlier, air density affects skydiving speed. In less dense air at higher altitudes, terminal velocity is higher.
### Conclusion
The average speed of a skydiver is influenced by a combination of factors, including body position, altitude, and air density. Experienced skydivers can reach speeds ranging from 90 to 180 mph in different positions during freefall. Understanding these factors allows skydivers to control their speed and enjoy a safe and thrilling experience.
