We know gravity is everywhere even though we can't see it.We know it pulls on every stone and every drop of water. It pulls on everything. The gravity of the earth pulls everything towards the center of the earth.You know this when you try to lift a heavy stone. Gravity pulls it down. The more the stone weights, the more gravity pulls on it. To lift the stone, you must pull up harder than gravity pulls down. The earth has gravity and the moon also has gravity. The moon has less gravity than the earth has. This means the moon's gravity does not pull as hard as the earth's gravity. Do you weigh 60 kilograms?
