On ground-going vehicles it's quite easy. Basically you use a mechanism that Count the number of turns a Wheel does, and compare that with how long time it took. If you know the circumference of the tire, you get the speed easily enough.

What is speed and velocity of a car that traveled a total of km north in 1.5?

The speed of the car is the rate at which it covers distance, measured in kilometers per hour. The velocity of the car is the rate at which it changes position, including direction, measured in kilometers per hour in a specific direction. Without the value of distance traveled or the specific direction (north) covered, the speed and velocity of the car cannot be determined.


How does a car's average speed differ from 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.


What does the speedometer of a car measure?

It measures the rate of travel.IE. the speed the car is traveling at.The speedometer of a car measures speed. It is measured in miles per hour or kilometres per hour (mph or kph).The speedometer of a car measure the instantaneous speed.


How is the speed of an aircraft measured?

The speed of an aircraft is measured using an airspeed indicator, which measures the speed at which the aircraft is moving through the air. Groundspeed, on the other hand, is the speed at which the aircraft is moving over the ground and is measured using GPS technology.


How could 2 observers measure a different speed for the ame moving object?

Both of the people could have measured the speed at a different time. Even if one measured the speed a split second before the other, the speeds could be different. This is because in that exact moment the speed is referred to as the INSTANTANEOUS RATE....Imagine a car starting up...it gradually speeds up as it accelerates so in one second from now the car could have a much faster speed.

Is tempo measured in miles per hour?

No. Musical tempo may be measured in "beats per minute" (quarter notes). The speed of the "Ford Tempo" (midsize car, 1984 to 1994) was measured in mph.
