What is the speed you read on a speedometer?
instantaneous speed. =)
What is the speed you read from your speedometer called?
instantaneous speed
Does the speedometer of a car read average speed or instaneous speed?
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.
Does the speedometerof a car read average speed or instantaneous speed?
The speedometer in a car does not measure the car's velocity because velocity is an (A) vector quantity and has a direction associated with it (B) vector quantity and does not have a direction associated with it.
Does speedometer of a car read instantenous speed or average speed?
instantanous speed
Does the spedometer of a car read average speed or instantaneous speed how do you know?
To be pedantic... In a car with a digital speedometer, speed is NOT instantaneous in the sense that it is a measure of distance per unit time. It does this by measuring a change in distance over a very short period of time to *approximate* the instantaneous speed. If the time period is a small fraction of a second you wouldn't know the difference! For older cars with analog speedometers the speed is instantaneous as it directly translates the speed at which your wheels are turning.
What kind of speed is read by a car speedometer?
The average speed of the vehicle relative to the road.
Can you read the speed in reverse gear?
On the speedometer, no. It will indicate a speed but it will not be accurate.
What is the definition of instantaneous velocity?
Instantaneous velocity:Suppose the velocity of the car is varying, because for example, you're in a traffic jam. You look at the speedometer and it's varying a lot, all the way from zero to 60 mph. What is the instantaneous velocity? It is, more or less, what you read on the speedometer. I'm assuming you've got a good speedometer that isn't too sluggish and can change its reading quite quickly. Your speedometer is measuring the the average velocity but one measured over quite a short time, to ensure that you're getting an up to date reading of your velocity.So if you measure the displacement of the car over a time , you can use that to determine the average velocity of the car. What we want is to take the limit as goes to zero.Most of the time we'll be working with instantaneous velocity, so we'll just drop the instantaneous, and call the above vthe velocity.To justify that such a limit exists is something that you've hopefully had to grapple with already. For physics problems, this limit does indeed exist and gives the derivative
You have a Camaro 94 z28 with the 110mph speedometer. Will the speed be wrong if you change it to the 150mph speedometer?
The speed should read fine with a GM speedometer, as the 110 and 150 are calibrated to go into the same cars with the same transmissions.
Does a car has speedometer velocity are both?
A car has a speedometer. When you read the speed that it indicates, and you know the direction in which you're driving, then you know the car's velocity.
The speed you read on a speedometer is?
The speed you are travelling measured in miles per hour, or kilometers per hour, depending on where you live.
