| Question | Answer |
| Acceleration | The rate of change of velocity. Can be calculated from a velocity time graph |
| Braking Distance | The distance a vehicle travels under the braking force. Can be affected by weather conditions and car conditions. |
| Distance time graph | A plot of distance over time. Gradient is the speed at that point. |
| Elastic deformation | Non permanent deformation of a spring or elastic band. will go back to normal after deforming forces are removed |
| Elastic limit | Permanent deformation. Can not go back to it's original shape. Deforms plastically. |
| Friction | A force that opposes motion |
| Hooke's Law | The force acting on a spring is directly proportional to the extension, up to the elastic limit. |
| Newton's first law | If resultant force is 0 |
| Newton's second law | F=MA - Force is directly proportional to acceleration. Acceleration inversely proportional to mass. |
| Newton's third law | The forces that two objects exert on each other are: Equal and opposite. |
| Contact and Non contact forces | Contact: Force that acts on something physically Non-Contact: Force that acts on something from a distance; Not through contact. |
| Thinking Distance | Distance vehicle travels during driver's thinking time. Affected by drugs, alcohol, fog... |
| Velocity-Time graph | Velocity over time. Gradient = acceleration at that point. Area under graph = Distance |
