Science Summary
Gravity pulls objects to the ground anywhere on Earth. To begin, the gravitational pull of the Earth is the “attraction” that Earth exerts on an object or the object exerts on Earth. Gravity is a force. It forces things to drop or stay on the ground and not fly up into the air. The gravitational pull can be calculated by the mass of an object, the mass of the Earth, and the distance between the center of the Earth. Next, free fall is when objects are falling towards the ground. Therefore, an object that is in the air is always considered in free fall motion. A plane (when it is flying) is in free fall motion, but not in downward free fall motion. Finally, the less dense an object is, the
