What is the difference between mass and weight?

Question

Mass depends on location. Weight depends on the force of gravity.
Mass depends on the force of gravity. Weight is always the same.
Mass measures the force of gravity. Weight measures matter.
Mass is the same everywhere. Weight depends on the force of gravity.

Answer 1

The correct statement is:

Mass is the same everywhere. Weight depends on the force of gravity.

To elaborate:

• Mass is a measure of the amount of matter in an object and is measured in kilograms (kg). It does not change regardless of location.
• Weight is the force exerted by gravity on that mass and is measured in newtons (N). It varies depending on the gravitational field strength of the location (e.g., an object weighs less on the Moon than on Earth due to the lower gravitational pull).

So, while mass is constant, weight is variable and influenced by gravity.
