## How Fast Does a Skydiver Reach Terminal Velocity?
### Introduction
Terminal velocity is the maximum speed at which an object falling through a fluid (such as air or water) can travel. It is reached when the force of gravity acting on the object is equal to the drag force acting against it. For a skydiver, terminal velocity is typically around 120 mph (193 km/h).
### Factors Affecting Terminal Velocity
The terminal velocity of a skydiver is affected by a number of factors, including:
Body position: The position of the skydiver’s body can significantly affect their terminal velocity. A skydiver in a “belly to earth” position will experience more drag and reach terminal velocity more quickly than a skydiver in a “head down” position.
Surface area: The surface area of the skydiver’s body also plays a role in terminal velocity. A skydiver with a larger surface area will experience more drag and reach terminal velocity more quickly than a skydiver with a smaller surface area.
Weight: The weight of the skydiver also affects their terminal velocity. A heavier skydiver will experience more gravity and reach terminal velocity more quickly than a lighter skydiver.
Air density: The density of the air also affects terminal velocity. A skydiver jumping in denser air will experience more drag and reach terminal velocity more quickly than a skydiver jumping in less dense air.
### How Fast Does a Skydiver Reach Terminal Velocity?
The time it takes for a skydiver to reach terminal velocity depends on the factors listed above. In general, a skydiver will reach terminal velocity within 10-15 seconds of freefall.
### Conclusion
Terminal velocity is an important factor to consider for skydivers. By understanding the factors that affect terminal velocity, skydivers can better control their descent and avoid dangerous situations.
### Additional Information
The world record for the highest skydive is held by Alan Eustace, who jumped from a height of 135,890 feet (41,419 meters) in 2014.
The world record for the longest freefall is held by Patrick de Gayardon, who freefell for 5 minutes and 31 seconds in 2006.
Skydiving is a relatively safe sport, with a fatality rate of about 0.02%.
