Question

A question on air resistance using the parachute experiment. Make a parachute using plastic bag as the material for the canopy of the parachute. Drop parachute from a height to test how well it works.
Hope someone can help me with the following questions:
1) Does a larger plastic sheet drop faster or slower?
2) Make a cut in the middle of the sheet. What can you see?
3) What modifications allow the parachute to reach the ground the slowest?

So for Qn 1, larger plastic sheet drops slower? For Qn 2, parachute will fall straighter?? Will it fall faster or slower?? How to do Qn 3 (what modifications allow the parachute to reach the ground the slowest)? Thanks.
