During a football game, a student accidentally knocks similar gym bags, one empty and one full of shoes and clothes, off the back of the bleachers. If there is no wind resistance, which bag will hit the ground first?A The full bag will hit the ground first.B The empty bag will hit the ground first.C They will both hit the ground at the same time.D This cannot be determined because the dimensions of the bags are needed.
Question
During a football game, a student accidentally knocks similar gym bags, one empty and one full of shoes and clothes, off the back of the bleachers. If there is no wind resistance, which bag will hit the ground first?A The full bag will hit the ground first.B The empty bag will hit the ground first.C They will both hit the ground at the same time.D This cannot be determined because the dimensions of the bags are needed.
Solution
C. They will both hit the ground at the same time.
This is because the acceleration due to gravity is the same for all objects near the surface of the Earth, regardless of their mass. This principle is famously demonstrated by Galileo's Leaning Tower of Pisa experiment, where he dropped two balls of different masses from the tower and found that they hit the ground at the same time. The same principle applies to the gym bags in this scenario.

You are performing a physics experiment in the school gym. Your experiment uses two objects: a bowling ball and a basketball. These are the same size and shape, but the bowling ball is much heavier than the basketball. You take the balls to one side of the gym. Each ball starts off standing still. You then roll the balls towards the other side of the gym, applying the same amount of force to each ball. Assuming the gym floor is frictionless, conclude which ball will reach the far side of the gym first. Justify your answer using Newton's Second Law of motion.
