Make the parachute wider/bigger or make the parachute deeper. Make the thing pulling it down lighter. Hope this helps. =)
Depending on the mass of the payload, it would fall more slowly than usuall.
A parachute must have suspended weight in order to open. If you have no weight loading the parachute will fail.
Parachute has more drag (air resistance)
All parachutes are designed for one fundamental purpose: to slow the gravity-driven fall of an object -- often a person, sometimes inanimate cargo -- through the air. ... The greater the drag generated by a parachute, the more slowly a given object attached to that parachute will descend to Earth.
Depends what you mean by "better". A bigger parachute provides more wind resistant so if you were to jump out of a plane, you would want to go big. If your talking speed (like a running parachute) you would want a small parachute to accommodate how much harder you want to make your run
The surface area, mass and the shape of the parachute affect the time of fall of the parachutes. Also the height, where the parachute have been dropped from. ( There are more factors that this).
The word parachute comes from the French word para (such as in parasol) and chute (meaning fall). See the related link for more information.
In a hotter climate, there are more conventional currents thus meaning that there will be more hot air rising which will effectively slow down the parachute. So in Colorado it will fall faster than in a hotter climate.
well air resistance can make objects with a-lot of surface fall more slowly
well air resistance can make objects with a-lot of surface fall more slowly
Creep
The surface area of a parachute can be different sizes and weights. If the surface is smooth then the you will fall faster because the texture is smooth and the air will slip by it. if it is rough then it will be slower because the the air will come into the parachute slower.
