| Question | Answer |
|---|---|
| change in position relative to some fixed object or place ? | motion |
| distance traveled per unit of time ? | speed |
| total distance traveled divided by the time it takes to travel the distance ? | average speed |
| speed and direction ? | velocity |
| rate of change of in velocity over time ? | acceleration |
| property of all moving things ? | momentum |
| total momentum of any isolated system always remains the same ? | Law of conservation of Momentum |
| Newton ? | SI unit of force |
| An object at rest, remains at rest; an object in motion stays in motions; Inertia ? | Newton's 1st Law |
| Acceleration depends on an objects mass and force; action-reaction ? | Newton's 2nd Law |
| For every action there is an equal and opposite reaction ? | Newton's 3rd Law |
