| mass | the amount of matter in an object |
| volume | the amount of space an object occupies |
| units for mass | grams |
| units for volume (solid) | cm cubed |
| units for volume (liquid) | mL |
| inertia | an object's resistance to a change in motion (determined by mass) |
| density | the amount of matter per unit volume |
| density formula | d=m/v |
| density units (solid) | g/cm cubed |
