If Keanu and Marcellus are in a room where Keanu is standing on the floor and Marcellus is hanging from a bar on the ceiling by his knees, both facing the same direction, and they both drop a ball at the same moment, what happens to the balls?

Make your response very short.
Both balls will fall to the floor due to gravity. The ball that Keanu drops falls directly downwards towards the floor beneath him. The ball that Marcellus drops also falls directly downwards towards the floor, but since he is upside down, it heads in the same direction as Keanu's ball. Gravity acts on both objects in the same way, pulling them towards the Earth's center.
