I would call it current speed, not average speed.
The driver is checking the current speed of the vehicle, as indicated by the speedometer.
The speed you read from your speedometer is called your "indicated speed." This value represents the speed at which your vehicle's wheels are rotating, not necessarily your true ground speed due to potential inaccuracies in the speedometer reading.
no
instantaneous speed
instantanous speed
The speedometer on a vehicle shows the instantaneous speed, which is the speed of the vehicle at any given moment. It does not display the average speed over a period of time.
No. Instantaneous speed is shown on the speedometer.
It reads instantaneous speed, and tells you nothing about average speed.
A car's speedometer typically shows the instantaneous speed, which represents the current speed of the vehicle at any given moment. It does not show average speed or velocity.
In a car, the speedometer measured Instantaneous speed. This comes from the assumption that the car does not slow down and speed up fast enough for the speedometer to be able to give an average of the changing speed.
A car's speedometer typically shows the instantaneous speed, which is the speed at a specific moment in time. It does not show average speed or velocity, which would involve calculations over a longer period of time.
It reads instantaneous speed, and tells you nothing about average speed.
