Explain why a man using a parachute falls through air slowly while a stone falls through air very fast?
When an object falls through air, it experiences air resistance. This air resistance is a force that opposes the object's motion. The amount of air resistance an object experiences depends on the object's shape, size, and speed. A man using a parachute falls slowly because the parachute creates a large amount of air resistance. A stone falls very fast because it has a small amount of air resistance.
What force stops a parachute from falling too fast?
drag
Why is that when feather is placed on top of the book and dropped the feather drops as fast as the book?

What does the vent on the top of the parachute do?
The vent on top of the parachute helps air go through. If you didn't have a vent at the top you would be floating in the same place. The vent makes the parachute go down slowly but not fast enough to where you would drop.
Do shapes of ice cubes affect its melting?
