What is mass?
the weight of an object
the amount of matter that makes up an object
the amount of force it takes to move an object
the size of an object
Answered by YTD
How is force related to acceleration?
Acceleration works in inverse proportion to force.
Acceleration works in variable proportion to force.
Acceleration has no relationship to force.
Acceleration works in direct proportion to force.

Mass is defined as **the amount of matter that makes up an object**. It is a measure of the quantity of matter in an object, typically measured in kilograms or grams.

To clarify the other options:
- **Weight** is the gravitational force acting on an object and is dependent on the mass and the acceleration due to gravity.
- **The amount of force it takes to move an object** relates to Newton's second law of motion (Force = Mass × Acceleration) and is not a direct definition of mass.
- **The size of an object** is more related to its dimensions or volume rather than its mass.

So the correct answer is "the amount of matter that makes up an object."
