| matter | anything that has mass and takes up space |
| volume | the amount of space taken up by an object |
| liquid volume labels | liters or milliliters |
| meniscus | the curve at the surface of a liquid |
| solid volume labels | cubic meters or cubic centimeters |
| regular solid volume | multiply length, width, and height |
| irregular solid volume | put objects in water and measure the amount of water is displaced |
| volume equals | one milliliter of water equals one cubic centimeter |
| volume tool | graduated cylinder |
| mass | the amount of matter in an object |
| mass tool | balance scale |
| mass labels | milligrams, grams, or kilograms |
| Why do scientists prefer mass? | mass never changes because of location |
| weight | a measure of the force of gravity on an object |
| source of gravity | comes from the center of the Earth |
| weight tool | spring scale |
| weight labels | newtons |
| compare mass & weight | one newton = 100 grams on Earth |
| inertia | the tendency of an object to resist a change in motion |
| compare mass & inertia | mass is a measure of inertia |
