Weight vs. Mass: Understanding the Difference
Although often used interchangeably in everyday language, weight and mass are different physical quantities:
Mass
Mass is a measure of the amount of matter in an object. It remains constant regardless of location. Mass is measured in kilograms (kg), grams (g), etc.
Weight
Weight is the force exerted on an object due to gravity. It varies depending on the gravitational field. Weight is technically measured in newtons (N).
On Earth, we typically use weight and mass interchangeably because the gravitational field is relatively constant. However, an object's weight would be different on the Moon or Mars, while its mass would remain the same.
