Air molecules create an upward force that impacts the free fall of objects on the surface of the Earth, differing form the way an object would fall in vacuum.
Question: What kind of objects should be used for experimentation if we want to limit the impact on our experimental measurement of the acceleration of gravity. And what objects should be avoided? Why is a basketball chosen

Galileo’s law of falling bodies states that the rate of fall caused by gravity is the same for all objects, regardless of weight. This means that all objects have a free-falling acceleration of 9.8m/s2. However, a significant contradiction …
