Does the odometer of the car measures the average speed of the vehicle. Justify your answer
Answers
Answer:
The odometer may be defined as a device or an instrument which is used for the measurement of the distance travelled by a vehicle, such as a bicycle or car. An odometer device may be a mechanical device or electronic device depending upon the type of components used in the device. It may be the combination of both electronic and mechanical (electromechanical devices). The other name of an odometer is “odograph”.
Thus an odometer measures the total distance travelled by the vehicles from the starting point to the destination point.
Odometer, or odograph, is a device that measures the distance travelled by an automobile based on the perimeter of the wheel as the wheel rotates. The odometer gives us only the measure but doesn’t show the direction of velocity. The odometer measures the scalar quantity – the speed of the car. The device may be electronic or mechanical or a combination of the two.
- Most odometers work by counting wheel rotations and assume that the distance travelled is the number of wheel rotations times the circumference, which is the standard tire diameter times pi (3.146).
- Some errors will be caused in the odometer, if non-standard or severely worn or underinflated tires are used. It is common for odometers to be off by several percent.
