What is the relationship between mass (m) and weight (g) in physics?

In physics, mass (m) and weight (g) are related but not the same. Mass is the amount of matter in an object, while weight is the force of gravity acting on that object. Weight is calculated by multiplying an object's mass by the acceleration due to gravity (g). The relationship between mass and weight is that weight is directly proportional to mass, meaning that as mass increases, weight also increases.
