Instantaneous speed cannot be measured because it is a theoretical construct. It is the speed that an object has at one particular moment, but measuring the speed of an object necessarily involves several moments so you can only measure the speed over some finite amount of time.

Slope of a displacement time graph?

It is the instantaneous speed in the direction in which the displacement is measured.


What is the difference between instantaneous speed and speed?

Instantaneous speed is the speed of an object at a specific moment in time, while speed refers to the average rate at which an object covers distance over a period of time. Instantaneous speed gives the speed at a precise instant, whereas speed provides an overall measure of how fast an object is moving.


What can speed be measured by?

it can be measured by distance covered and time taken. Speedometer is a device to measure the speed Average Speed = total distance/ total time; speedometers use other correlates to estimate instantaneous speed.


How does a car average speed differ from its instantaneous apeed?

The average speed of a car is how fast it averages over a span of time. Instantaneous speed is how fast the car is moving at any given time which is measured using a real-time speedometer.


Is instantaneous speed final speed?

No instantaneous speed is not final speed.


How does a car's average speed differ it's instantaneous speed?

The average speed of a car is how fast it averages over a span of time. Instantaneous speed is how fast the car is moving at any given time which is measured using a real-time speedometer.


Does the speedometer of a car read average speed or instantaneous speed?

instantaneous speed


How is instantaneous speed different from average?

The average speed is the speed that it takes to travel a certain distance in a certain time. Average speed is determined by dividing the distance traveled by the time taken to get there. Instantaneous speed is a certain speed at any given time.


An objects speed at a particular moment in time is called?

Instantaneous Speed.


What is speed measured in an infinitely small time interval?

Speed measured in an infinitely small time interval is known as instantaneous speed. This is the speed at a specific moment in time, as opposed to average speed which considers the total distance traveled over a given time period.


What does it mean when someone says a car has a trap speed?

The trap speed is the measured "instantaneous" speed of the vehicle at some timing location, for instance at the end of a 1/4 mile run.


What do you mean by instantaneous speed?

Instantaneous speed is the speed of a body at any one instant. There is really no such thing as the instantaneous speed, it is merely the average speed over a very short space of time.
