Having ones arms apart improves stability in freefall. A skydiver usually adopts a stable spread body position.

How do you be careful whilst skydiving?
Safety is everything in skydiving. Without it, there would be many accidents and it would be shutdown by the CAA in the UK. So there are many things which can improve safety:A proper and indepth certification system which enables new skydiver to be taught the basics. The first rung on the ladder is called the A-certificate.The British Parachute Association which manages all the dropzones where sky diving takes places and has committees designed to constantly improving safety.Each skydiver jumps with 2 parachutes - a main and a reserve.All new skydivers must jump with an AAD - an Automatic Activation Device. This tiny computer will open your reserve parachute automatically if the jumper has not done themself at a low altitude.Each dropzone is inspected every 2 years to ensure compliance with safety.Once a skydiver reaches the age of 40, they must have a medical certificate signed by their doctor.I jump in Lincolnshire at a dropzone called skydiving.co.uk. They run regular additional qualifications and coaching weekends which are designed to improve the skills of a skydiver. Doing so reduces the chances of accidents.
What happens to a skydiver before they open their parachute?
They jump out of the plane and accelerate to terminal velocity.
How does a open parachute increase the air resistance of a falling skydiver?
by increasing surface area
What does a skydiver hope to see above him just after the ripcord is pulled?
When he or she wants the parachute to open
When a skydiver opens their parachute they move upwards?
The skydiver doesn't move upwards when the parachute opens. In reality, the parachute creates air resistance, slowing down the skydiver's descent until they reach a safe landing speed. This process is what allows the skydiver to land safely.
Can you die if you hit deep snow while skydiving and a parachute doesn't open?
Yes
How does an open parachute increase the air resistance of a falling skydiver?
An open parachute increases air resistance by creating a large surface area that catches and slows down the air around it. This creates drag that counteracts the force of gravity, slowing the skydiver's descent. The inflated canopy also increases the overall mass of the skydiver-parachute system, further enhancing the air resistance.
How many women have survived skydiving accidents?
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.
How does an open parachute increase the air resistance of a falling skydriver?
An open parachute increases air resistance by capturing and deflecting air molecules. This creates drag force that opposes the skydiver's downward motion, slowing their descent. The increased air resistance allows the skydiver to fall at a more manageable and safer speed.
What does the phrase' track off' mean?
in skydiving, it is when jumpers turn and "fly" away from each other to open their parachutes.
Compare the effects of gravity and air resistance on a falling skydiver before and after she opens her parachute.?
-- The force of gravity is unchanged before and after.-- The force of air resistance on the skydiver is greater before, and less after,because she is falling slower after the parachute opens.-- The effect on her of air resistance is greater after the parachute is open. Theincreased air resistance itself acts on the parachute, and its effect is transferredto the skydiver through her harness.
How does an open parachute increase air resistance of a falling skydiver?
An open parachute increases air resistance by creating a larger surface area that pushes against the air as the skydiver falls. This increased surface area results in greater air resistance, slowing down the skydiver's descent. The parachute helps to counteract the force of gravity and allows the skydiver to descend more slowly and safely.
