| 8188449149 | Linear Momentum | The quantity of motion of a moving body. Vector quantity. For various objects is the sum of the individual quantities. | 0 | |
| 8188449150 | Impulse | The amount of force acting on an object times the time in which this force is acting. | 1 | |
| 8188449151 | Perfectly elastic collision | Two objects collide and conserve their Kinetic Energy & momentum. Objects bounce off of each other. |  | 2 |
| 8188449152 | Perfectly inelastic collision | Two colliding objects stick together to become one; momentum is conserved, but Kinetic energy is not. | | 3 |
| 8188469389 | Equation for momentum | p=m v | 4 | |
| 8188472479 | Equation for impulse | J=Ft | 5 | |
| 8188474984 | Units for momentum | kg m/s | 6 | |
| 8188480854 | Units for impulse | N s | 7 | |
| 8188493578 | Impulse -momentum theorem | Impulse is equal to the change in momentum |  | 8 |
| 8188532938 | Conservation of momentum | The total momentum of an isolated system is conserved (unchanged) after a collision or explosion as long as no external forces act on the system. | 9 | |
| 8188693784 | Pool balls hitting each other, bat & baseball are examples of... | Elastic collisions | 10 | |
| 8188698188 | Clay balls hit & remain stuck, cars crash & become tangled are examples of... | Inelastic collisions | 11 | |
| 8188728129 | When objects collide in-elastically the Kinetic Energy is not conserved, where does it go? | Becomes heat and sound. | 12 | |
| 8188783286 | The forces which act between the objects of a system. | Internal forces | 13 | |
| 8188789052 | The forces that act on the objects of a system from outside the system. The agent of the force is not a part of the system. | External forces | 14 | |
| 8188818036 | The point at which the total mass of a system of masses can be considered to be concentrated. | Center of mass | 15 | |
| 8188835026 | Amount of time the impact lasts | time of impact | 16 | |
| 8188838047 | How hard an object hits | force of impact | 17 | |
