<u>I am so sorry if this is incorrect! But after some research, this is what I found. </u>

Aristotle said that there are 4 elements: Earth, Wind, Water, Fire. Objects made of earth (like a rock) will want to go the center of the universe (center of the Earth). Things made of fire want to go to the place where fire is. I guess this would be the Sun - or somewhere up. Aristotle also said that a heavier object will fall at a faster speed.
