What is the term for the quantity of material contained within a body?

The term describing the quantity of material contained within a body is mass. Mass refers to the amount of matter in an object and is a fundamental property that does not change regardless of the object's location. It is measured in units such as grams or kilograms and is a scalar quantity, meaning it has magnitude but no direction.

In contrast, force pertains to an interaction that causes an object to be accelerated. It is expressed in newtons, and it is influenced by both mass and acceleration. Volume describes the amount of space an object occupies, typically measured in cubic units, such as liters or cubic meters, but does not directly relate to the quantity of material. Weight is the force exerted by gravity on an object’s mass, varying based on gravitational acceleration and also measured in newtons. Understanding the distinction between these terms helps clarify concepts in physics and material science related to mass and its implications for other properties.
