| 13364930525 | Acceleration | Change in velocity. Can be a change in direction, positive (speeding up) or negative (slowing down). |  | 0 |
| 13364930529 | Magnitude | A scalar quantity | 1 | |
| 13364930537 | Motion | A change in the position of an object over time from a reference point. |  | 2 |
| 13364930544 | Example of velocity | Nemo swims 37 m/s South to Wallaby Way in Australia. |  | 3 |
| 13364930545 | Speed | the distance traveled by an object in a given amount of time. |  | 4 |
| 13364930546 | Example of speed | Nemo swims 58 m/s |  | 5 |
| 13364930548 | Velocity | speed of an object and its direction of motion; changes when speed, direction or both changes | 6 | |
| 13364930552 | vector | An quantity that has a magnitude and direction | 7 | |
| 13364930555 | displacement | the total distance traveled by an object regardless of direction from start to finish | 8 | |
| 13364930556 | distance | the amount traveled from a certain spot. | 9 | |
| 13369600902 | If an object is moving northward and slowing down, then the direction of its acceleration vector is | South | 10 | |
| 13369588737 | If an object is moving eastward and slowing down, then the direction of its velocity vector is | East | 11 | |
| 13369591457 | If an object is moving eastward and slowing down, then the direction of its acceleration vector is | West | 12 | |
| 13460890782 | Newton's First Law | An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. | 13 | |
| 13460895928 | Newton's Second Law Equation | Force = mass x acceleration | 14 | |
| 13460909605 | Newton's Second Law | The acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. | 15 | |
| 13460915299 | Newton's Third Law | For every action there is an equal and opposite reaction | 16 | |
| 13460923107 | balanced forces | Equal forces acting on an object in opposite directions |  | 17 |
| 13460924748 | unbalanced forces | Forces that cause a change in the motion of an object |  | 18 |
| 13460942499 | Inertia | The tendency of an object to resist a change in motion. Inertia depends on mass. |  | 19 |
| 13460966687 | Mass | the amount of matter in an object | 20 | |
| 13460970658 | Force | a push or pull on an object |  | 21 |
| 13460977144 | action-reaction forces | pair of forces involved in an interaction that are equal in magnitude and opposite in direction |  | 22 |
