| Question | Answer |
|---|---|
| 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. |
| Inertia depends on what | Mass and force |
| Force and and inertia are what | Directly proportional |
| Mass and inertia are what | Directly proportional |
| 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 |
| What is friction | A force between two forces in contact |
| What is static friction | Friction that opposes two forces from sliding last each other |
| What is sliding friction | Friction that swathe motion of two forces sliding last one another |
