if the parachute is wider there will be more air resistance which slows things down and if there are holes the air can pass through which decreases air resistance. so the wider it is the slower it is.the lighter it is the slower it is
No. In many movies it appears that someone opening a parachute flies up in the air. However, this is because of the perspective of the camera, which continues falling while the person slows down. Gravity continues to pull the person down to the ground, the parachute only slows them down.
A parachute will slow down a free-fall by catching the air rushing past you. It's large, bag-like shape greatly contributes to the air resistance working against the gravitational pull, and so slows your fall down a point that it is no longer dangerous.
The two main forces acting upon a parachute when it falls is gravity and wind resistance. Gravity pushes the parachute down, however wind resistance slows the fall by pushing the opposite way to gravity.
