Motion definitions

1. The exact speed of an object at a specific given point (13, 5)
7. The time taken to process a stimulus and trigger a response to it. It is affected by alcohol, drugs and tiredness (8, 4)
10. The sum of thinking distance and braking distance for a driven vehicle (8, 8)

2. The rate of change of velocity (12)
3. Distance over time for the entire region of interest (7, 5)
4. 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 (10, 6)
5. The distance travelled between the brakes being applied and the vehicle coming to a stop. It is affected by the vehicle and road conditions (7, 8)
6. An object is said to be in free fall when the only force acting on it is the force of gravity (4, 4)
8. The rate of change of displacement. It is a vector quantity and so has both a direction and a magnitude (8)
9. 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 (12)
