| Inertia | The tendency of an object to resist a change in its motion |
| Mass | The amount of matter in an object; a measure of the inertia of an object, which depends on the amount of matter the object contains |
| Weight | The force of gravity acting on an object |
| Newton's first law of motion | The state of motion of an object does not change as long as the net force acting on the object is zero |
| Newton's second law of motion | The acceleration of an object is equal to the net force acting on it divided by the objects mass |
| Momentum | The product of an object's mass and it's velocity |
| Law of conservation of momentum | law stating that the momentum of a system does not change if net force acts on the system |
| Newton's third law of motion | Whenever one object exerts a force on an object, the second object exerts an equal opposite force on an object |
