Skydiving

Terminal velocity is determined not by mass (weight) but by air resistance. When the gravitational force is matched by the drag force (air resistance), acceleration becomes zero. If a skydiver did two dives, one with a backpack filled with feathers and one with the same backpack filled with lead, the terminal velocities of each dive would be the same, as the air resistance induced by the diver did not change from dive to dive. Weight alone does not influence terminal velocity. However, it is likely that a heavy person will also have a large projected area (surface area), increasing the drag coefficient, and effectively lowering the terminal velocity.

A heavy person is therefore likely to have a slower terminal velocity than a light person, assuming heavy people are also large and bulky.

The previous answer is completely wrong.

The differential equation describing sky divers is

dv/dt=g-k/m*v

where x denotes the distance fallen, and k describes the gas viscosity and interaction with the diver. This equation is an approximation, but one that is very valid in the case.

The solution to the equation is

v=(g m)/k + exp(-((k t)/m)) C[1]

where C[1] is a constant term determined by initial conditions. The terminal velocity is a velocity determined by long term behavior. For large t, the exp decay term goes to zero, so

v terminal = (g m)/k

Thus, it depends on m.

I agree. As a general rule, light jumpers need to add weight, (increase Mass) to fall at a similar rate to average sized jumpers. A Tandem pair require a drogue parachute in the freefall phase to increase drag and reduce velocity to compensate for the extra mass of the tandem passenger. If you threw a cat out of a plane and jumped out soon after, you would barely have time to wave as you flew past. The cat might even survive this cruel act. I once filmed a tandem where the TM was 115kg and the passenger was 105kg. I used my SCUBA weight belt with about 5kgs of weight to keep up. The company eventually saw the light and restricted him to passengers, 70kgs or less.

It depends what goes wrong

The maximum speed you can reach is also known as terminal velocity and this is the speed at which your mass is resisted by the air. Typically in a belly to earth body position, this is around 120mph. It takes around 10 seconds to reach this speed. The minimum exit height is 2500ft and would not reach this terminal velocity before they need to deploy their parachute. Most skydivers jump from a lot higher - between 10,000ft and 15,000ft. This gives them a freefall time of over 45 seconds and therefore they reach terminal velocity.

Once the parachute is open, the decent rate is less than 10mph, so no you do not hit the ground at maximum speed in answer to your question.

Terminal Velocity.

You trust that the person packing it knew what they were doing and that they weren't on drugs or half-asleep at the time. Otherwise, you could learn how to pack your own and then do so for every jump; each time it will be packed as correctly as you want.

Just about anywhere but the best weather for jumping in March will be in Florida or out west in California or Arizona. www.floridaskydiving.com www.skydiveaz.com www.skydiveperris.com

You would say

"We went sky diving last Sunday"

"Did you just hear that Susan went Sky Diving?"

"James jumped out of the airplane without hesitation and it was the greatest example of sky diving I have ever seen"

"Folding" the parachute to skydive, more commonly referred to as packing, is a skill that all student skydivers need to learn before gaining their first license. To learn to pack a skydiving parachute, seek a licensed skydiver or an experience packer for demonstration and a helper during the learning process. There are videos available to aid the learning process, such as Packing Made Simple. If learning through a video, always seek a licensed instructor, certified rigger, or instructor to ensure the parachute has been packed correctly before use.

Yes

Clear skies and low winds (between 5 and 15mph) are perfect for skydiving.

The short answer is yes. If you are otherwise well, the pressure changes that occur in normal skydive altitudes wont cause you any problems. I would not recommend SCUBA diving. If you have no issues on commercial aircraft, there should be no problem.

I would recommend that you consult a doctor who is an aviation specialist in the first instance and go for a Tandem jump at no higher than 4000m.

I would not recommend any jumps above that altitude especially if you have any noticeable breathlessness in some situations.

Law enforcement SWAT. You're not likely to find much of anything in the military in the realm of Special Operations which doesn't have to at least be parachute qualified.

It is called a drogue chute and it stabilizes the jumper and pulls the main parachute out of the container or pack.

1/2 g t2.

1/2 x 9.81m/s2 x 64

9.81 x 32 313.92m.

1000-313.92=686.08

heat makes a parachute fly because when hot air goes into a balloon shape it blows up and then lifts into the air it acts like helium o yeahhhh

) If flying high has been your lifelong wish, paragliding, hang gliding and flying small planes could be some of the thrilling activities you could explore. However, before embarking, there is a caveat you need to pay head to. Any airborne sport requires passion underlined with guts. This is not for the faint hearted and necessitates strong nerves and a reasonable level of fitness. So if you think you have it in you, here are a few adventure-sports clubs that you could check out.

Greenhorns can go for the simplest form of flying called paragliding. The nearest take off zones are at Nandi Hills and Ramanagaram. A para glider is an inflatable wing fixed onto a harness; the flier sits on this harness and launches the glider by running off ravines and cliffs. Sounds simple, yet a couple of days of training are mandatory. For guidance and information get in touch with any of the city's clubs, some of which include, Ozone, Gethna and Spark, Angel, Bangalore Aero Sports, Agni Aero Sports, Adreno and Sahas Vertigo Expedition Pvt. Ltd.

2) Agni Aviation, has the following Aero-Sports activities:

- Para Sailing

- Para Gliding

- Powered Hang Gliding

- Gliding

- Microlight Flying

- Sky Diving

Firstly there are two types of parachutes, the old fashion "roundies" and the modern ram air square chutes.

I presume that the hole in the top of round parachutes creates an airflow through the canopy during deployment (opening) which reduces the chances of a malfunction during this critical phase. If not for this airflow, the flow of air around the unopened canopy would create an air pressure differential between the inside and outside of the fabric and the resultant suction would tend to keep the canopy in a collapsed state, not a good thing to happen as the ground rushes up at you.

It would also make the canopy more steerable.

The holes in the front of a square canopy are sealed at the back of the chute and allow the chute to pressurise into its aerodynamic shape.

People skydive because they are bored

Perhaps the question should be, " How long after a wisdom tooth extraction should I wait prior to skydiving?"

That would depend on whether it was a Tandem jump or a sport jump. As long as you feel ok there should be no problem as far as a Tandem jump. You will be required to fill out a form and should inform your TM if you have any concerns. I would consider it prudent to wait for a couple of days to a week, depending on recovery.

As a sport jumper, you should not jump if you are still on painkillers and feel sore and sorry for yourself. I would consider a week minimum would be a good idea. The sky is not going to go away. It can be very difficult when the skies are blue and you havent jumped for a while because of the weather.

If first you don't succeed, skydiving is not for you.

Probely a booger.

Death

The momentum of the diver with the gravity against the thinner air in the altitude and the position of your body cause you to slow down your fall.

The plane was on the ground, not flying in the air.
