Mass is the amount of matter in an object. It is typically measured in kilograms (kg) or grams (g).
Mass and weight are often used interchangeably, but they are not the same. Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity acting on an object. Mass remains constant regardless of gravity, while weight can change based on the strength of gravity.
The mass of an object can be determined by using a balance scale or by measuring the object's weight and then dividing by the acceleration due to gravity (9.8 m/s² on Earth).
Mass is typically measured in kilograms (kg) or grams (g). In some cases, it may also be measured in other units such as pounds (lb) or ounces (oz).
The mass of a box directly affects its weight, as weight is a product of mass and gravity. The heavier the box, the greater its weight will be under the same gravitational pull.
