What is Newton's first law | An object at rest stay at rest and an object in motion stays in motion in the same direct and speed |
What is Newton's second law | The acceleration of an object is in the same direction as the net force on the object |
What is Newton's third law | For every action there is an opposite and equal reaction |
Force and direction are what | Directly proportional |
Mass and acceleration are what | Inversely proportional |
What is inertia | Is a property of matter because matter resists change in motion. |

What is a force | A push or pull |
What is net force | Result of both forces on an object |
What is an unbalanced force | Forces that are unequal in size and opposite in direction and results in no motion |
What is a balanced force | Forces that are equal in size and opposited in direction |
