How is the moon's orbit around the earth related to an apple falling from a tree?
The earth's gravity keeps the moon in orbit, and also pulls objects toward the ground.
The earth, the moon, and an apple are all spherical, so they all have gravity.
The moon's gravity holds apples on tree branches, while the earth's gravity pulls apples toward the ground.
