Final answer:
The question covers the adjustment of following distance based on speed in Physics, emphasizing safety and the non-linear relationship between speed and stopping distance. It also explains instantaneous versus average speed.
Step-by-step explanation:
The question 'Always adjust your following interval according to the speed you're going' relates to the concepts of speed and motion in Physics. An increase in speed should be accompanied by a larger following distance to ensure safety, as it takes longer to stop when traveling faster.
This principle is grounded in the understanding that a car's final stopping distance is not directly proportional to its speed due to the physics of acceleration and deceleration. For example, a car traveling at 50 mph will need more distance to come to a full stop than one traveling at 30 mph, which is why speed zones are often reduced in certain areas like near schools.
Instantaneous speed, as shown on a speedometer, is the speed of a vehicle at a specific instant, unlike average speed, which is calculated over a period of time regardless of direction.
