How many G's does a skydiver experience in freefall?

In summary, An electric motorbike was reported to be able to go from 0 to 60 miles per hour in less than one second, giving the driver a G-force three times more than skydivers experience during freefall. However, this does not necessarily mean that the force is zero, as it depends on the context of the situation. Additionally, the product has been marketed with associations to cool and dangerous activities, but there may be some discrepancies in the reported information about the G-force experienced.

Isn't that ... zero?
But how many kW per second does it do.

Free fall under the influence of gravity means the force is 1g.

Depends... if you mean when he's in free fall, then yes it's 0. If you mean when he hits the ground because his parachute failed to deploy... well, the g-force of that sudden deceleration is pretty hefty :)

For sky-divers the term "free-fall" includes descending through the air at constant speed, and the force felt is 1 G of aerodynamic drag, opposing gravity.

That's almost 3times the G force felt by a Tuba player in a marching band!

:rofl:

The sense of associating the product with a cool item ...

At the begin it's zero. Then 1g for a while. Maybe they mean when you open the parachute.

Perhaps they meant that, but they said "during freefall". (EDIT: However, this is the only answer that makes any sense.)

And a force 3 times greater than that means this is one dangerous motorbike!

By that logic, an astronaut orbiting the Earth experiences slightly less than 1g, yet we refer to that as a 0g situation.

1. What is the average amount of G's a skydiver experiences during freefall?

The average amount of G's a skydiver experiences during freefall is typically around 1.2 G's. However, this can vary depending on factors such as body position, wind conditions, and altitude.

2. Can a skydiver experience more than 1 G during freefall?

Yes, a skydiver can experience more than 1 G during freefall. As the diver gains speed, the amount of G's they experience will also increase. This can reach up to 3 G's in some cases.

3. Is the amount of G's a skydiver experiences consistent throughout the entire freefall?

No, the amount of G's a skydiver experiences during freefall is not consistent. It varies depending on the speed and position of the diver, as well as external factors such as wind resistance. It can also change as the diver opens their parachute.

4. How does the amount of G's a skydiver experiences compare to other extreme sports?

In comparison to other extreme sports, skydiving typically involves a lower amount of G's. For example, during a roller coaster ride, a person may experience up to 4 G's, while in a Formula One race car, a person can experience up to 5 G's.

5. Are there any risks associated with experiencing high G forces during skydiving?

Yes, there are risks associated with experiencing high G forces during skydiving. These can include nausea, blackouts, and even injuries to the body. That is why it is important for skydivers to train and prepare their bodies for the forces they may experience during freefall.
