| Term | Definition |
|---|---|
| Meter | distance |
| Kilogram | mass |
| Pascal | Pressure |
| Seconds | Time |
| Meter/second | speed |
| Meter/second/second | acceleration |
| Newton | force |
| kilogram x meter/second | momentum |
| Groups and periods | vertical and horizontal |
| Be Condensate | close to absolute zero |
| Kinetic | movement |
| Half-life | amount of time it takes for half of the sample to decay |
| Energy | Ability to do work |
| Net balance | Forces equal zero |
| 1st Law | Object in motion stays in motion; object at rest stays at rest unless an unbalanced force acts on it. |
| Inertia | property of matter in which changes in motion are resisted. |
| Weight | mass x acc of gravity |
| 2nd Law | Mass is inversely proportional to force Acceleration is directly proportional to force |
| Gravity and supporting | What two forces act on a stationary object on the ground. |
| acceleration | change in velocity (speed up slow down, or change direction) |
| Free falling objects | constant acceleration, 9.8m/s/s |
| Instantaneous | Starting point |
| Displacement | object location from start to finish |
| Slope of distance and time graph | speed |
| Atoms | building blocks of matter |
| Gas | indefinite shape, indefinite volume |
| liquid | Indefinite shape, definite volume |
| Solid | Definite shape and volume |
| Gas Pressure | increases in a container due to temp, volume changes, or amount of gas particles |
| Condensation | gas to liquid |
| evaporation | liquid to gas |
| freezing | liquid to solid |
| solid to liquid | melting |
| solid to gas | sublimation |
| gas to solid | deposition |
| Nucleus of atom | dense positively charged |
| electrons | 1/2000th of the size of a neutron or proton, negatively charged |
| Protons | positive charge, number of them make the element what it is, number of them is the atomic number |
| neutrons | neutral or no charge about the same size as a proton |
| How many neutrons | Mass number-atomic number |
| Medeleev table arrangement | atomic mass |
| Properties of metals | good conductors, malleable, ductile |
| Periodic table | farthest left most reactive |
| Valence electrons | control reactivity, increase as you move left to right on the periodic table |
| Alkali metals | one valence electron very reactive |
| Alkaline Earth | two valence electrons very reactive |
| Balancing equations | make sure your element numbers add up on each side, multiply coefficients to the subscript numbers |
| Frame of reference | perspective based on what you are looking at |
| Inverse Relationship | when one variable increases the other decreases |
| Direct Relationship | when one variable increases the other increases |
| Scalar | measurement with only magnitude |
| Vector | measurement with direction and magnitude |
| Ductile | Pulls into wires |
| Malleable | Pounded into thin sheets |
| y axis | vertical axis, dependent variable |
| x axis | horizontal axis, independent variable |
| Probability | Chance something will happen |
| Force | any push or pull on an object |
| Speed | Distance divided by time |
| Motion | change in position of an object |
| Velocity | speed with a direction |
