Mass
MASS is defined as a measure of inertia. Because mass and inertia are so similar, they are often used interchangeably.
Mass has a second definition which is the amount of matter an object contains. Because mass is a measure of inertia, and because mass is a measure of the amount of matter in an object, the more matter an object contains, the more inertia it has.
In general, an object which contains more matter (or has a greater mass) has a larger inertia, and it resists changes in motion more. I repeat: If an object has a LARGE mass, it resists changes in motion A LOT, and if an object has a SMALL mass, it resists changes in motion A LITTLE.

An object's mass is independent of its location. In other words, an object's mass does not change when it is moved from one place to another. Click HERE to learn a little bit more about mass. |
