Skydiving

In most states the age requirement is 18 years, but it can vary from state to state and from county to county. Sixteen years is probably the youngest a diver can be, but if you're really interested, you should contact the U.S. Parachute Association and ask about age limits in different drop zones in your area to be sure.

Breast implants make little difference to physical activity. Running and jumping are unaffected. If the implants are large it could affect the ability to reach across the chest, which has implications for some activities, such as racket sports.

You need to be able to speak and understand the language in which the course will be taught. You need to be in reasonable physical condition and be able to learn through experience and practice.

Wear comfortable clothing. More than likely you will put on a jumpsuit over what you are wearing, not to mention the parachute. Don't wear anything too constrictive. Closed-toe tennis shoes are a must.

Terminal velocity, if you are flat toward the ground is about 180 feet per second; so time is distance/speed = 1000 feet/180 = 5.5 seconds. If you roll up like a ball terminal velocity may be as high as 280 feet per second. and time would be about 3.5 seconds.

That is a personal opinion. I personally don't think its scary, I enjoy it, though I get a rush from it. I can easily see, however, why someone would say it is scary. There are a lot of risks involved and if you don't know what you're doing there is a lot that can go wrong. So, the answer to your question really just depends on who you ask.

The sky diver's parachute, also called a canopy, is used to slow the falling rate of a sky diver from terminal velocity (about 120mph) to a much slower and safer rate that the person can land without harm.

By definition, if he is accelerating, then it is an unbalanced force ... which means he JUST jumped out the plane and his downward speed in increasing. Once he reaches a particular speed (called terminal velocity; lets call it for a general case of about 110 mph), the force of DRAG will be equal to the force due to gravity and he will no longer be accelerating, no longer increasing in speed, and he will then have balanced forces.

Since the variables are always changing, drag will change with the most subtle changes in the skydiver's orientation either intentionally or unintentionally and the air resistance is constantly changing with increase in density, the forces will never be truly balanced. The effect of both forces will seesaw between one or the other being dominant. Terminal velocity is achieved when that process is minimal.

It is of note that the effect of gravity itself is changing but over a skydive, the effect is negligible and may be ignored.

Without on board oxygen, the limit is about 15,000 feet. With on board oxygen, jumpers can go to about 20,000 feet. With bail out oxygen bottles, the altitude is limited by the type of aircraft used. The record for highest parachute jump is just shy of 103,000 feet. http://en.wikipedia.org/wiki/Joseph_Kittinger

Not really. Training for competition might require some running or jumping, but few fun jumpers bother with conditioning. Skydiving itself is tiring, but not really all that aerobic.

Who is packing your parachute is sort of like a reflective quote meaning "who is looking out for you and keeping you safe." You don't want to burn your bridges with those who "pack your parachute" such as the friends who keep you company and love you. They're the ones who help you when you need it most... like a parachute.

Tandem jumps can cost anything from $100 to $600 depending on things like whether you want a video and where you jump. It is best to shop around for the best deal. You do not usually have to pay for gear frental; everything is included in the cost of the jump. The one exception to this is membership, some centres add this cost on, so be sure to ask.

This can be referred to as the "opening force" of the canopy.

Yes and no. Yes because you can fold it back up into its sack. But some kinds of parachutes can not be folded back into its sack. For example a normal nylon parachute can. But a space parachute cant.

Thousands. A skydiving accident can be life threatening, or a sprained thumb. Accidents are usually minor- a less than perfect landing might give a twisted ankle or knock the wind out of you. A bad exit might bang a knee or shoulder. All of these things have happened, but they are all fairly rare.

You must be at least 18 years old to tandem skydive. Try visiting http://www.skydiveorange.com/faq.htm , they have tons of information regarding skydiving restrictions and requirements.

There is a formula that works quite well. The first 1000ft takes 10seconds. This is because the initial velocity with respect to the ground is zero so therefore the average velocity to this point is half terminal. Thereafter, it takes 5 seconds for every 1000ft.

Therefore a jump from 12000ft will give you 7000ft of free fall with a deployment at 5000ft. That is 10 sec to 11000ft, then 6 times 5 seconds to 5000ft, a free fall period of 40 seconds.

Keep in mind a heavier Tandem passenger will have a bit less time, and a small Asian woman or a child will have a bit more.

More bang for your buck, call Jenny Craig. Check out the Tandem Instructors and go for the smallest. That will give you a bit more FF.

Because of the lower air pressure at higher altitude, this formula is not quite so good for 16000ft or 20000ft Tandems.

You need to be a generally healthy human being with an average fitness level. 100kg - 110kg need to be assessed on the day.

They had a chute out!

This is debated with some saying it happened in the 17th century or even earlier in the 12th century by the Chinese.

However, the first documented case of a parachute jump (not a freefall skydive) was by Jacques Garnerin in 1797.

The first freefall with a packed parachute was by Georgia Broadwick in 1914. She opened her parachute herself instead of using a static line.

Depends what you mean by "better". A bigger parachute provides more wind resistant so if you were to jump out of a plane, you would want to go big. If your talking speed (like a running parachute) you would want a small parachute to accommodate how much harder you want to make your run

A parachute floats by "catching" the air to slow descent.

The weight of the sky diver has minimal effect on freefall time. Body position and amount of surface area exposed for wind resistance to affect are the two largest factors, and are interrelated to one another.

To start with there is gravitational attraction. As soon as the skydiver starts falling, (s)he will experience the drag force due to air resistance. The gravitational force is essentially constant but the drag increases as the diver's velocity increases until it equals gravity. The diver is the falling at terminal velocity and will continue to do so until the parachute is operated.

there are three main parts that come with a parachute. there's the chute, the draglines, and the weight or mass (could be a human). then there's also the hole in the top of the chute.
