## Does a Skydiver Accelerate Once He Falls?
The answer to this question is yes. Once a skydiver falls from an airplane, they experience acceleration due to the force of gravity. The acceleration due to gravity is approximately 9.8 m/s^2, which means that the skydiver’s velocity increases by 9.8 m/s every second.
### Why Does a Skydiver Accelerate?
A skydiver accelerates because there is a net force acting on them. The force of gravity is pulling them down towards the Earth, and the force of air resistance is opposing their motion. However, the force of gravity is greater than the force of air resistance, so the net force is acting in the downward direction. This net force causes the skydiver to accelerate downward.
### How Fast Does a Skydiver Accelerate?
The acceleration of a skydiver depends on several factors, including their weight, the density of the air, and the shape of their body. However, most skydivers accelerate at a rate of approximately 9.8 m/s^2. This means that their velocity increases by 9.8 m/s every second.
### What Happens Once a Skydiver Reaches Terminal Velocity?
Once a skydiver reaches terminal velocity, their acceleration stops. This happens when the force of gravity is equal to the force of air resistance. At terminal velocity, the skydiver is no longer accelerating and their velocity remains constant.
## The Factors That Affect a Skydiver’s Acceleration
There are several factors that can affect a skydiver’s acceleration, including:
– Weight: Heavier skydivers accelerate faster than lighter skydivers.
– Density of the air: Skydivers accelerate faster in dense air than in thin air.
– Shape of the body: Skydivers who have a more streamlined body shape accelerate faster than skydivers who have a less streamlined body shape.
## The Effects of Acceleration on a Skydiver
The acceleration of a skydiver can have several effects on them, including:
– Increased heart rate: The acceleration can cause the skydiver’s heart rate to increase.
– Increased breathing rate: The acceleration can also cause the skydiver’s breathing rate to increase.
– G-forces: The acceleration can create G-forces on the skydiver’s body. These G-forces can cause the skydiver to experience blackouts, tunnel vision, and loss of consciousness.
## Conclusion
Skydivers do accelerate once they fall from an airplane. The acceleration is due to the force of gravity, and it continues until the skydiver reaches terminal velocity. The acceleration can have several effects on the skydiver, including increased heart rate, increased breathing rate, and G-forces.
