Newton's Laws, Part 2
| Term | Definition |
|---|---|
| Action-Reaction | Newton's 3rd Law is sometimes called |
| force | This is what is equal, but opposite in Newton's 3rd Law |
| pairs | Forces always occur in these |
| equal | Colliding forces are always this in size |
| momentum | Mass times velocity calculates this |
| mass x velocity | Momentum is calculated using this formula |
| kg-m/s | The SI derived unit for momentum is this |
| transferred | What happens to the momentum from one object to another in a collision |
| conserved | In an isolated system, the total amount of momentum is |
| gases | Rockets propel themselves by pushing off of their |
| rocket | In rocket propulsion, the force pair is rocket on gases, gases on |
| mass | The gases accelerate out of the rocket so fast because of the rocket's great amount of |
| 1st | Newton's laws of motion about inertia |
| 2nd | Newton's law showing the relationship of acceleration to force and mass |
| 3rd | Newton's law of action-reaction forces |
| velocity | Momentum is mass times this |
| p | Momentum is represented by the letter, |
| acceleration | Force divided by mass is this |
| simultaneously | Force pairs occur at this time |
| conservation | The total momentum before a collision is equal to the total momentum after a collision is the law of __ of momentum. |
