The acceleration due to gravity doesn't change near the earth's surface, no matter
what the cause of your fall is, or what position you assume during the fall, or what
you're wearing. But a parachute sets up significant force opposite to gravity, because
of air resistance. Since the acceleration is proportional to the net force, it can be
reduced when there is considerable force canceling a significant fraction of the
gravitational force.
Speed or acceleration have no effect on gravity.
Acceleration does not effect gravity. It is rather the other way round. Gravity can affect the rate of acceleration.
Acceleration is the result of the total force. Use Newton's Second Law, whichis usually written as:F=maSolving for acceleration:a = F/mPlease note that the F (force) refers to the net force - the sum of all forcesthat act, in this case, on a person with a parachute. In this case, it is the sum(the vector sum, to be precise) of the force of gravity (downward), and theforce of friction (upward). After a short while, these forces will be balanced -the net force, and therefore the acceleration, will be zero.The parachute has no effect on the acceleration due to gravity. It just usesair to create a force that works in the direction opposite to gravity, and thatreduces the acceleration of the body that's wearing the parachute.
No effect. All masses experience the same acceleration due to gravity.
Acceleration simply refers to the rate of change of a velocity. You might say that the effect of an acceleration - any acceleration - is therefore a change of velocity.
The acceleration affects the weight of the person and object

-- 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.

Yes it does. It has mass and like all other objects it is attracted to other masses. Throwing a parachute out of a plane will demonstrate this. It will head for Earth.
On earth, the mass of an object has no effect whatsoever on its acceleration due to the force of gravity. All objects fall with the same acceleration, regardless of their mass. Any observed difference is due entirely to air resistance.
The effect of increasing the height of the track on the acceleration of the object is that more work is required to accelerate. It increases the gravity.
