## How Fast Do You Fall When Skydiving with a Parachute?

Skydiving is an exhilarating activity that involves jumping out of an airplane and freefalling towards the ground. A parachute is then deployed to slow the descent and allow for a safe landing. But just how fast do you fall when skydiving?

The answer to this question depends on several factors, including:

– Body position
– Air resistance
– Weight
– Parachute size and type

### Body Position

The body position during freefall affects the speed at which you fall. A streamline position, with the arms and legs extended and the head tucked in, minimizes air resistance and allows for faster speeds. On the other hand, a spread-eagle position, with the limbs extended, increases air resistance and slows the descent.

### Air Resistance

Air resistance is a force that opposes the motion of an object moving through the air. The greater the air resistance, the slower the object will fall. The density of the air also plays a role, with higher altitudes having lower air density and less air resistance.

### Weight

Weight is another factor that influences the speed of a skydiver. Heavier skydivers experience greater gravitational force and fall faster than lighter skydivers.

### Parachute Size and Type

The size and type of parachute used affect the rate of descent. Larger parachutes provide more surface area for air resistance, slowing the fall rate. Different types of parachutes, such as square or ram-air, also have varying drag characteristics that impact the speed of descent.

## Typical Freefall Speeds

During freefall, a typical skydiver can reach speeds of up to 120 mph (193 km/h) in a streamline position. However, experienced skydivers performing dives with extreme body positions, such as head-down or flat spins, can exceed speeds of 170 mph (274 km/h).

## Parachute Deployment and Descent

Once the parachute is deployed, the descent speed decreases dramatically. A typical parachute used for recreational skydiving will slow the descent rate to around 10-15 mph (16-24 km/h).

## Factors Affecting Parachute Descent Speed

The descent speed after parachute deployment can also be influenced by factors such as:

– Parachute canopy size
– Canopy shape
– Lines and risers
– Wind conditions

## Conclusion

The speed at which you fall when skydiving with a parachute depends on a combination of factors. Body position, air resistance, weight, and parachute size and type all play a role. Typical freefall speeds can reach up to 120 mph, while parachute deployment slows the descent rate to around 10-15 mph. Understanding these factors is essential for ensuring a safe and enjoyable skydiving experience.
