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. |
