Physics
| Question | Answer |
|---|---|
| inertia in motion | momentum |
| a change in momentum | impulse |
| momentum unit | kgm/s |
| impulse unit | Ns |
| how much momentum do you have at rest? | 0 kgm/s |
| velocity and momentum are ___ related | directly |
| If an impulse occurs with less force, then it occurred over a ____ time period. | longer |
| To change the speed more, exert ____ force. | more |
| To change the speed less, exert your force for ____ time | less |
| To lower the force of impact from a collision, you must ____ the time | increase |
| This piece of safety equiptment increases the time of an impact reducing the force from an impulse. | helmet |
| A collision where the objects bounce off each other. | elastic |
| A collision where the objects move off together as one. | inelastic |
| A collision that starts with one piece and ends with more than one piece. | explosion |
