In unit 3, we focused on acceleration and the variables that also affect it like velocity, time and distance. According to a theory of Galileo's, discovered that freely falling bodies, heavy or light, have the same, constant acceleration and that this acceleration is due to gravity. We spent today trying to discover that on our own through our own experiments.
An example we were shown in class was that if a tennis ball and a volleyball were dropped at the same height at the same time (in an air-less environment), even though the mass of each ball was different, they would land at the same time. This is because the pull of gravity is always constant. Heavier things don't fall faster then lighter things (in an air-less environment, as air resistance is the reason paper is an exception on Earth)
