Instantaneous speed - This is the speed of an object at any given moment in time, often represented as the rate of change of distance with respect to time at a specific instant.
Average speed - This is the total distance an object travels over a period of time divided by the total time taken, often represented as the rate of change of distance with respect to time over an interval.
Constant speed - This is when an object travels at the same speed over a period of time, meaning the instantaneous speed and average speed are equal.
An example of instantaneous speed is the speedometer reading in a car at a particular moment in time. For instance, if a car is moving on a highway, the instantaneous speed of the car is the speedometer reading at that exact moment, which can vary as the driver accelerates or slows down the car. Another example is the speed of a bullet fired from a gun, which is the speed at which it leaves the barrel of the gun.
