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 forces affect the sport of sky diving?
Gravity pulls the skydiver towards the centre of the earth (downwards force). The air causes wind resistance, slowing the sky diver down (upwards force). The wind can also cause a slight sideways force upon the skydiver.
Is it true that the steady speed reached by a skydiver is called the terminal velocity?
Yes. Not just a skydiver; anything that falls long enough will eventually reach "terminal velocity", which means that it will continue falling at a constant speed, because the force of gravity and the force of air resistance are in balance.
What forces are acting on a skydiver?
Under free fall, the only force acting upon an object is the force of gravity. But realistically, there is also the force of friction from the air (Air Resistance) that opposes the force of gravity.
Why won't a skydiver's speed continue to increase until his or her parachute opens?
Once a skydiver jumps off the plane, they will begin picking up speed. However, as the speed of the skydiver increases, the amount of air resistance acting upon them will also increase. The skydiver will continue to accelerate while his or her weight is greater than the air resistance. When the force of the air resistance becomes equal to the weight of the skydiver, the skydiver will stop accelerating and will continue falling at a constant speed, this is known as the terminal velocity. While travelling at terminal velocity, the skydiver will be able to adjust his or her body position in a way that will increase or decrease the air resistance and allow the diver to alter their speed. Releasing his or her parachute will drastically increase the amount of air resistance and therefore slow their descent significantly.

what force is increased after the skydiver open parachute?
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.
What force pulled a skydiver to the ground?
gravity
A feather is in freefall when the force of gravity is greater than the force of air resistance is equal to the force of air resistance is less than the force of air resistance is the only force acting?
"Free fall" means that gravity is the only force acting on a body.

How much air resistance acts on a 500 N skydiver that falls at her terminal velocity?
500 N is pressumably the weight, due to gravity. "Terminal velocity" means that the forces are in balance; the total force acting on the skydiver are zero. This is only possible if there is a 500 N force due to friction, to counteract the weight.
How is air resistance used in a sentence?
air pressure is when air gets pressed down
When a skydiver has reached terminal speed what is the air resistance equal to?
Fnet=Fgravity-Fair resistance At terminal velocity Force Net = 0 during this time Fgravity = Fair resistance if you weight is 85kg Fgravity = Mass x G = 85x 9.8 = 833N your at terminal velocity when Air resistance is equal to 833 Newtons
