1. Mass: The Moon has significantly less mass than the Earth. Gravity is directly proportional to mass, meaning a larger mass exerts a stronger gravitational pull. The Moon's mass is about 1/81st that of Earth.
2. Radius: The Moon also has a smaller radius than Earth. The force of gravity is inversely proportional to the square of the distance between objects. This means that the farther away you are from the center of an object, the weaker its gravitational pull. The Moon's smaller radius means you're closer to its center of mass, but this effect is outweighed by the much lower mass.
3. Density: The Moon's average density is lower than Earth's. This means that for a given volume, the Moon contains less mass, further contributing to its weaker gravitational pull.
In summary:
* The Moon's lower mass and smaller radius combine to result in a gravitational force that is about 1/6th that of Earth.
* This means that an object weighing 100 pounds on Earth would weigh only about 17 pounds on the Moon.
