| Question | Answer |
| Describe the difference between balanced and unbalanced forces. | Unbalanced forces cause motion or a change in the state of motion in an object. Balanced forces do not cause a change in an objects state of motion. |
| 56300/2 | 23150 |
| Does the inertia of an object change as it's velocity does? | No inertia is not affected by velocity |
| What is newtons 1st law of motion. | An object in moving stays at a constant velocity unless an unbalanced force acts upon it. |
| How do airbags assist in an accident? | It keeps you from banging your head on the dashboard as it inflates then deflates. |
| How does friction increase when a larger force pushes to surfaces togeather. | As the surfaces get closer the number of static friction increases. |
| What are the 4 types of friction that we studied in class that one event. | Applied- The Force applied by one object onto another. Air resistance- The force applied on an object moving through the air. Normal- The force exerted on a resting stable object. Tension- The force transmitted by two objects pulling on each other. |
| What is newtons second law of motion? | the acceleration of an object is dependent upon two variables - the applied acting upon the object and the mass of the object. |
| Formula for acceleration. | f=m X a |
| The formula for net force. | A= Force over Mass |
