Are the forces acting on the parachute contact or non contact forces?

What is the relation between the gravity and the drag force?

Hypothesis: The parachute which is made of handkerchief will drop faster than the one made of plastic bag.

Steps : 1-Cut a square from the plastic bag and a square from the paper that is the same size as the handkerchief. 2-Cut twelve 6”pieces of string. 3-Tie one piece of string to each corner of the plastic square. 4-Tie one piece of string to each corner of the handkerchief. 5-Punch a hole in each corner of the paper and tie a piece of string through each hole. 6-Attach a ball of clay to the bottom of the plastic square and handkerchief. Use the dangling string pieces for the attachment. 7-Stand on a chair or ladder. 8-Drop each parachute at the same height from the elevated location. 9-Have another person record the time from the moment the parachute is release until it hits the ground.

Does the height of the parachute affects the time it takes to drop?

Does the load carried by the parachute affects it's falling?

what is the relation between the surface area, air force and the parachute drag?
