The difference between instantaneous speed and average speed is crucial in understanding speed measurements.
Instantaneous speed is the speed of an object at a particular moment in time. In the scenario of a police officer using a radar gun, the speed measured is the instantaneous speed of the vehicle at that moment. This is different from average speed, which is calculated over a certain time interval and may not capture the exact speed of the vehicle at a particular instant. Instantaneous speed gives a precise measurement at a single point in time.
