Physics students conduct an exploration activity into falling objects and how they are affected by air resistance. The students decide to drop three objects from the shoulder height of the tallest student in the class. They drop a flat sheet of paper, a balled up sheet of paper, and an agenda book. Which statement below best describes what they observed?

Question

Question 9 options:

The agenda book hit the ground first and the two sheets of paper took a little longer because they had less mass than the agenda book.

The agenda book and the balled up paper both hit the ground at approximately the same time while the flat sheet of paper took much longer to hit because it experienced air resistance.

The agenda book hit the ground first because it had the greatest mass. The balled up sheet of paper hit the ground a couple of seconds later because it had much less mass. The flat sheet of paper took the longest time because it was light and had a lot of air resistance.

All the objects hit the ground at the same time because there was no air resistance in their classroom.

Answer 1

The agenda book hit the ground first because it had the greatest mass. The balled up sheet of paper hit the ground a couple of seconds later because it had much less mass. The flat sheet of paper took the longest time because it was light and had a lot of air resistance.
