## Resource summary

 Question Answer 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
