The balled up and flat sheets of paper both fell faster than the physics book because they have less mass. The balled up and flat sheets of paper both took longer to fall than the physics book because they have less mass. The balled up and flat sheets of paper both hit the ground at approximately the same time as the physics book. The balled up sheet of paper hit the ground at approximately the same time as the physics book. The flat sheet took longer to fall due to air resistance.
Students in a physics class were given several objects and asked to explore the nature of objects falling. The students drop each object from a height of 1.5 m. They use a timer to determine how long it takes each object to hit the ground. One of the students forgets to record the data for the time it took the samples of paper to fall. Their results are presented in the table as shown.
