| Matter | Anything that has volume and mass |
| Volume | The amount of space that something occupies or the amount of space that something contains |
| meniscus | the curve at a liquid's surface by which you measure the volume of the liquid |
| mass | the amount of matter that something is made of; its value does not change with gravity |
| gravity | a force of attraction between objects that is due to their masses |
| weight | a measure of the gravitaitonal force exerted on an object, usually for us- Earth |
| newton (N) | the Si unit for force |
| inertia | the tendency of all objects to resist anychange in motion |
| physical property | a property of matter that can be observed or measured without changing the identity of the matter |
| density | the amount of mater in a given space; mass per unit volume |
| chemical property | a property of matter that describes a substance based on its ability to change into a new substance with different properties |
| physical change | a change that affects one or more physical preperties of a substance; most physical changes can be reversed |
| chemical change | a change that occurs when one or more substances are changed into entirely NEW SUBSTANCES with different properties; cannot be reversed using physical means |
