| law of conservation of momentum | when some bodies constituting an isolated system act upon one another, the total momentum of the system remains constant |
| Mass | A coherent, typically large body of matter with no definite shape. |
| Momentum | : a property of a moving body that the body has by virtue of its mass and motion and that is equal to the product of the body's mass and velocity |
| Speed | Rapidity of movement or action |
| Velocity | The speed of something in a given direction |
| instantaneous speed | In kinematics, the speed of an object is the magnitude of its velocity |
| Displacement | The moving of something from its place or position. |
