Distance over time for the entire region of interest
Average speed
2 of 13
The distance travelled between the brakes being applied and the vehicle coming to a stop. It is affected by the vehicle and road conditions
Braking distance
3 of 13
The direct distance between an object's starting and ending positions. It is a vector quantity and so has both a direction and a magnitude
Displacement
4 of 13
Plots showing how displacement changes over a period of time. The gradient gives the velocity. Curved lines represent an acceleration
Displacement-time graphs
5 of 13
An object is said to be in free fall when the only force acting on it is the force of gravity
Free-fall
6 of 13
The exact speed of an object at a specific given point
Instantaneous speed
7 of 13
The motion of an object that is fired from a point and then upon which only gravity acts. When solving projectile motion problems, it is useful to split the motion into horizontal and vertical components
Projectile motion
8 of 13
The time taken to process a stimulus and trigger a response to it. It is affected by alcohol, drugs and tiredness
Reaction time
9 of 13
The sum of thinking distance and braking distance for a driven vehicle
Stopping distance
10 of 13
The distance travelled in the time it takes for the driver to react. It is affected by alcohol, drugs and tiredness
Thinking distance
11 of 13
Plots showing how velocity changes over a period of time. The gradient gives acceleration. Curved line represent changing acceleration
Velocity-time graphs
12 of 13
The rate of change of displacement. It is a vector quantity and so has both a direction and a magnitude
