A parachute works by trapping air underneath, but when the air is trapped the pressure increases and some of the air has to escape. If there were no hole in the center of a round parachute, such as the military 'chutes used in WW2, the excess air would have nowhere to escape except under the edges of the 'chute, which would cause increasingly violent oscillation and quickly the collapse of the 'chute, which would drop the parachutist to the ground at high speed and kill him. The central hole allows a controlled release of the air pressure in the 'chute, preventing oscillation and the collapse of the 'chute.

What does gravity have to do with parachutes?
Air makes parachutes possible. Gravity makes them necessary.
Why speed of parachutes becomes constant?
Terminal velocity. When the parachutes cannot fall any faster.
Why does the rate of drop change in parachutes?
Parachutes increase the wind resistance experienced by a falling object, thereby slowing the speed of decent.
How can air Resistance be useful?
Try parachutes.
How does gravity and air resistance affect parachutes?
Gravity and air resistance are the main forces acting on a parachute. Parachutes are pulled towards the ground by gravity, and if there was no parachute, the guy attached to the chute would turn into tomato paste. So parachutes are designed to create the maximum amount of drag (which is air resistance) so the whatever attached lands undamaged. So basically, parachutes create air resistance to reduce the effects of gravity
