Chapter 2, Problem 2.1DQ
Does the speedometer of a car measure speed or velocity? Explain.
Expert Solution & Answer
To determine
The speedometer of the car measure the speed or velocity.
Answer to Problem 2.1DQ
Speedometer does not measure the direction of the car this means that speedometer will not measure the velocity of the car. Therefore, the speedometer is measure speed of the car.
Explanation of Solution
The speed is defined as the ratio of the distance travel by the particle to the time taken by the particle. Speed is a scalar quantity.
The velocity is defined as the ratio of the displacement of the particle to the time taken by the particle. The velocity is a vector quantity and the direction of velocity is same as the direction of displacement.
Conclusion:
Speedometer does not measure the direction of the car this means that speedometer will not measure the velocity of the car. Therefore, the speedometer is measure speed of the car.
