SUMMARY
The discussion clarifies the distinction between weight and mass, emphasizing that mass is a measure of the quantity of matter, constant across different gravitational fields, while weight is the gravitational force acting on that mass. Mass is measured in kilograms (kg), whereas weight is measured in Newtons (N). The relationship between the two is defined by the equation Weight = mass * g, where g represents the acceleration due to gravity. Common usage often conflates the two terms, but understanding their scientific definitions is crucial for accurate communication in physics.
