Final answer:
Mass is a constant measurement of matter in kilograms, while weight is the force due to gravity measured in newtons. Weight changes depending on the gravitational pull at a specific location, whereas mass does not. The correct statement that distinguishes these two concepts is that weight is a measure of gravitational pull.
Explanation:
Difference Between Weight and Mass
The concepts of mass and weight are fundamental in physics and often confused. Firstly, mass is a measure of the amount of matter in an object, and it remains constant regardless of location. It is measured in kilograms (kg) or grams (g).
On the other hand, weight is the force exerted by gravity on an object. It varies depending on where the object is in the universe because it is influenced by the strength of the gravitational field. Weight is measured in newtons (N), which is a unit derived from the equation: weight = mass x gravitational acceleration (W = m*g).
Therefore, the correct statement explaining how weight is different from mass is: Weight is a measure of gravitational pull. Here are some key differences summarized:
- Mass is constant, while weight can change based on gravitational force.
- Mass is measured in kilograms, whereas weight is measured in newtons.
- Weight depends on the location (e.g., an object weighs less on the Moon than on Earth).
