Why does being farther from earth's center of mass cause you to weigh less?

Weight is the force exerted by gravity on an object, which depends on both the mass of the object and the gravitational pull it experiences. As you move farther from Earth's center of mass, the gravitational force decreases due to the inverse square law, which states that gravitational force diminishes with the square of the distance. Consequently, if you are at a higher altitude or further from Earth's center, you experience a weaker gravitational pull, resulting in a lower weight.
