How is matter and weight related?

Answer 1

Two pieces of matter (mass) exert the force of gravity upon one another. The more mass, the more force. Here on Earth, we call the force of gravity upon an object its weight. Take a stone, for instance: The stone attracts the Earth, and the Earth attracts the stone. The force of this attraction is called the stone's weight. The exact relationship is given by Newton's law of universal gravitation: F=G*m1*m2/R**2, where G is a constant that applies to all matter; m1 and m2 are the masses of the two attracting bodies, respectively; and R is the separation between their centers of gravity.

Answer 2

Matter refers to the substance that makes up physical objects, while weight is the measure of the force of gravity acting on an object's mass. The weight of an object can change depending on its location (e.g., it would weigh less on the moon compared to Earth), but its mass (which is a measure of the amount of matter it contains) remains constant.
