Frage | Antworten |
Action force | The force exerted by one object or another, which is matched by a reaction force that the second object exerts on the first object |
Reaction force | The force exerted by one object on another in response to an action force that the second object exerts on the first object |
Resultant force | The overall force resulting from a combination of separate forces |
Accelerates | The rate of change of velocity over time; measured in m/s squared |
Gradient | The slope of a graph showing the relationship between between the two variables |
Deceleration | Negative acceleration, that is, the rate of change of velocity over time; measured in m/s squared, when the object is slowing down |
Stopping distance | Thinking distance + braking distance |
Thinking distance | The time it takes for a driver to recognise a hazard and apply the brakes |
Braking distance | The distance taken to stop from the moment braking begins |
Turbulence | Rough flow |
Terminal velocity | The velocity at which the air resistance on a falling object exactly balances the force of gravity so that the resultant force is zero and no further acceleration occurs |
