What is the difference between weight and mass?

In the context of matter and physical properties, the key difference between weight and mass lies in their definitions. Mass refers to the amount of matter in an object and is typically measured in kilograms (kg). On the other hand, weight is the force exerted on an object due to gravity and is measured in newtons (N). In simpler terms, mass remains constant regardless of location, while weight can change depending on the gravitational pull. Therefore, while an object's mass will be the same no matter where it's located, its weight may vary depending on the strength of gravity.
