Experiment #1 (Left Picture):

In the first experiment, the student drops a sheet of paper and a crumbled ball of paper from the same height at the same time. The student determines that the paper ball will hit the ground faster than the sheet of paper. Explain why the ball of paper falls faster than the sheet of paper using the vocabulary from Unit 4.
To receive full credit for this item, your response must:
Explain why the sheet of paper and paper ball fall at different rates even though they are made of the same material. You will lose a point if your answer does not include the vocabulary term air resistance. 2pts.).

The paper ball falls faster than the sheet of paper because of air resistance. Air resistance is the force that opposes the motion of an object as it moves through the air. The crumpled paper ball has a smaller surface area compared to the sheet of paper, which means there is less air resistance acting on it. This allows the paper ball to overcome air resistance more easily and fall faster than the sheet of paper.
