Mass (m)

Definition

Mass refers to the amount of matter an object contains. It is a measure of the inertia or resistance to changes in motion.

Think of mass as the number of people on a roller coaster. The more people there are, the harder it is to start or stop the roller coaster.

Weight: Weight is the force exerted on an object due to gravity. It depends on both mass and acceleration due to gravity.

Inertia: Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to mass.

Density: Density is a measure of how much mass is contained within a given volume. It can be calculated by dividing mass by volume.
