| density | the mass of matter per unit volume |
| buoyancy | the measure of the upward force that a fluid exerts on an object that is submerged |
| Archimedes principle | states that the bouyant force is equal to the weight of the fluid displaced by an object |
| fluid | a form of matter that flows when a force is applied |
| pressure | a force applied to a fluid. Pressure acts in all directions |
| Bernoulli's principle | a relationship that described energy conservation in a fluid |
| strength | the ability to maintain shaped under the application of force |
| elasticity | the ability to be stretched or compressed and then return to original size (rubber band) |
| brittleness | the tendency to crack or break; the opposite of elasticity (glass) |
| ductility | the ability to bend without breaking (steel) |
| crystaline | solid with a regular orderly arrangement of atoms (most solids on earth) |
| amorphous | solid with a random, jumbled arrangement of atoms |
