Detailed explanation-1: -It constantly moves around us. Without the force of gravity from the Earth, it would just float away into space. This mix of velocity and distance from the Earth allows the Moon to always be in balance between fall and escape.
Detailed explanation-2: -Newton’s first law of motion tells us that if no force acts on a moving object, the object will continue moving in a straight line. But because gravity does act on the Moon, it falls beneath the straight-line path it otherwise would follow (Figure 2).
Detailed explanation-3: -Since the Moon is smaller, and has much less mass, it pulls with less gravity. In fact, if you could stand on the surface of the Moon, you would experience only 17% the force of gravity that you would experience on Earth.
Detailed explanation-4: -If the Earth’s gravity did just suddenly disappear we would no longer have a force keeping us on the ground. The Earth would keep spinning, as it does, but we would no longer move with it; instead we would move in a straight line, upwards.
