Gravity

Cory the Clown with a little help from juggling balls explains the law of gravity.

Without gravity, we would be floating. Gravity keeps us on the ground. Gravity has been thought about throughout history. Gravity is a force that attracts objects towards one another. The earth has gravitational pull and keeps us on it. The sun has gravitational pull and keeps the planets orbiting around it. Every pair of objects has a gravitational attraction. The bigger the mass (stuff lumped together), the greater the pull. The closer together the objects are, the stronger the gravitational pull. This is why objects that are dropped fall onto the ground and don't fall up

Fun Fact: Black holes exist when big masses have pull so great they keep collapsing on themselves. Black holes are present far away in our universe.
