| a change in position | displacement |
| the entire length of an object's path | distance |
| any position to the left of the origin | negative |
| any position to the right of the origin | positive |
| speed: scalar OR vector | scalar |
| velocity: scalar OR vector | vector |
| displacement: scalar OR vector | vector |
| a vector that represents the sum of 2 vectors of | resultant |
| time is always on this axis | x |
| the ratio of an objects displacement to the amount of time | average velocity |
| the velocity of an object at a given point in time | instantaneous velocity |
| a straight line on a position-time graph | constant velocity |
| a line on a position-time graph curved upward | positive acceleration |
| dots equally spaced apart | uniform motion |
| dots progressively getting farther apart | non-uniform motion |
| allows you to determine your car's instantaneous velocity | speedometer |
| allows you to determine your car's average velocity | odometer |
| when there is NO air resistance | free fall |
| on earth it equals 10 m/s/s | g |
| velocity component of projectile that's constant | horizontal |
| velocity component of projectile accelerates | vertical |
