| Momentum = | mass x velocity |
| inertia in motion is the same as | momentum |
| The product of the force and the time interval | impulse |
| Ft = | the change in momentum |
| If the momentum is changed over a short time | the force is great |
| If the momentum is changed over a long time | the force is smaller |
| To accelerate an object you must apply | an outside force |
| Net momentum before collision = | net momentum after collision |
| elastic collision is | rebound without lasting deformation or heat |
| inelastic collision is | deformation, make heat, and or stick together |
| Law of Conservation of Momentum | Momentum cannot be created or destoryed |
| If you double the mass of a given moving object you ____ the momentum | double |
| Conservation of Momentum is closely related to Newton's | Third Law |
| Two objects reach the ground at the same time but with different ___ | momentum |
| A 4 kg ball has a momentum of 12 kgm/s. What is the velocity | 3 m/s |
| A clay ball with a momentum of 1 unit hits another ball initially at rest.. After the collision the balls have a momentum of | 1 unit |
| If a bug hits your windshield which undergoes the greater change in momentum? | Both are the same |
| 1 kg on earth weighs | 10 newtons |
| 4 kg on earth weighs | 40 N |
| The time the force acts | Impulse |
| The impulse equation | FT |
| Delta MV= | change in momentum |
| A car hits a large dump truck. The force is greater for | neither - due to 3rd law |
| A car hits a dump truck. The impulse is greater for | neither - time and force are equal |
| Car hits a dump truck. Acceleration is greater for | Car - 2nd law |
