| Matter is defined as | anything with mass and volume. |
| Matter is made of | tiny particles that are always in some motion. |
| The common states of matter | solid, liquid, gas and plasma. |
| Temperature | how fast the particles the make up matter are vibrating |
| Heat | is how many particles there are in some matter and how fast they are moving |
| Element | the most basic type of matter that is still unique. |
| protons, neutrons and electrons. | the three main particles in atoms(also quarks) |
| number of protons(atomic number) | determines the identity of an element |
| Matter is described by its | physical and chemical properties. |
| Periodic table is organized by.. | atomic number, electron configuration, similar properties. |
| Elements can bond together to form | chemicals other than elements. |
| There are three types of bond: | ionic, covalent and metallic. |
| The valence electrons determine how | a substance bonds. |
| We studied 4 types of reactions... | synthesis, decomposition, single replacement and double replacement. |
| Chemical equations are balanced using... | coefficients |
| pH levels of acids are | less than 7 |
| pH levels of bases are | greater than 7 |
| pH is neutral | 7 |
| Polymers | many monomers linked together. |
| Speed = | Distance÷Time |
| Velocity | speed in a certain direction. |
| Slope | a useful tool to understand data. |
| Newton’s 1st law | Things do what they are doing unless acted on by unbalanced force. |
| Newton’s 2nd law | Force= mass x acceleration |
| Newton’s 3rd law | every action force has an equal and opposite reaction force |
| Weight/Force units are | newtons(N) |
| Mass units are | grams(g) |
| Force is defined as | any push or pull. |
| Buoyancy | upwards force, caused by the weight of the fluid displaced |
| Work | applying a force through a distance |
| Work units are | joules(J) |
| Power = | work ÷ time. |
| Simple machines make work easier by | lowering force or lowering distance or changing direction. |
| Power units are | watts(W) |
