What is mass and weight

Mass is a measure of the amount of matter in an object. It is an intrinsic property of an object and does not change with location. Mass is typically measured in kilograms (kg).

Weight, on the other hand, is the force of gravity acting on an object's mass. It depends on the gravitational field strength of the location. Weight is a force and is measured in Newtons (N). The formula for weight is:

Weight = Mass × Acceleration due to gravity (g)

For example, an object with a mass of 10 kg on Earth (where g ≈ 9.8 m/s²) would have a weight of 10 kg × 9.8 m/s² = 98 N. If that same object were on the Moon (where g ≈ 1.62 m/s²), its weight would be 10 kg × 1.62 m/s² = 16.2 N, even though its mass remains 10 kg.
