| Inertia | The tendency of an object to resist any change in motion |
| Meniscus | The curvature of water in a container |
| Volume | The amount of space taken up or occupied by an object. The SI unit for a liquid volume is ml, for a solid it is cubic centimeters. |
| Mass | The measure of the amount of matter in an object. The SI unit used to express this number is the gram (g). |
| Gravitational Force | The force that keeps objects from floating off into space. |
| Weight | The measure of how much gravitational force is exerted on an object. The SI unit for expressing this force is the Newton (N). |
| Matter | Anything that has mass and takes up space (volume). |
| Density | The amount of mass (matter) in a given volume (space). the common SI unit for liquids is g/ml. How compact a substance is. |
| Physical Property | A property of matter that can be observed and measured without changing the matter's identity. |
