Here's why:
* Mass is a fundamental property of matter that represents the amount of matter in an object. It remains constant regardless of location or gravity.
* Weight is the force exerted on an object due to gravity. It is directly proportional to the object's mass and the gravitational acceleration.
Therefore, weight is the measurement of matter that changes depending on the force of gravity.
For example, an object with a mass of 10 kg will have a weight of 98 N on Earth (where gravitational acceleration is approximately 9.8 m/s²) but will have a different weight on the Moon due to the Moon's lower gravity.
