| A | B |
| vector | quantity with both magnitude and direction |
| scalar | quantity with only magnitude |
| resultant vector | sum of 2 or more vector quantities |
| component vector | vector added to another to create a resultant |
| projectile | object which moves in two dimensions, subject to the effect of gravity |
| parabola | shape of the path of a projectile in 2D motion |
| displacement | vector equivalent of distance |
| meter | standard unit for measuring displacement |
| speed | scalar quantity for change in position/time |
| velocity | vector equivalent of speed |
| horizontal | motion in this direction is unaffected by gravity |
| vertical | motion in this direction is always accelerating at 9.8 m/s2 |
| acceleration | vector quantity for change in velocity |
| distance | magnitude of difference in position (scalar) |
| second | standard unit used to measure time |
| delta | symbol used to represent change |
| Pythagorus | guy famous for a^2 + b^2 = c^2 for a right triangle |
| magnitude | describes the number, of quantity of a vector |
| direction | if this is not present, the value is a scalar quantity |
| freefall | condition of vertical motion experiencing only acceleration of gravity |
