| Question | Answer |
| What is the equation of momentum? | Momentum = mv |
| What is the conservation of momentum? | Total momentum of all objects before = total momentum of all objects after. (TMB = TMA) |
| What is an elastic collision? | A collision in which both kinetic energy and momentum are conserved. |
| What is an inelastic collision? | A collision in which only momentum is conserved. |
| What is the vector nature of momentum? | Direction is important, momentum to the right has a positive sign and momentum to the left has a negative sign. |
| What is the equation for impulse? | Ft = mv - mu |
| What does the term Ft mean? | Ft stands for impulse and is equal to the change in momentum. |
| What is Newton's 3rd law? | This law states that if an object A exerts a force on object B then object B will exert and equal and opposite force on object A. |
