Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the metrological traceability?Calibration ensures measurements are traceable to national or international standards
2. What is the key performance metrics assessed?Sensitivity, frequency response, linearity, and phase response
3. Why do we need a vibration calibrator?Because if sensors are wrong, the data could mislead engineers and lead to unsafe designs, like in airplanes or bridges.
4. How does a vibration calibrator work?It produces a precisely controlled vibration and compares the sensor’s response to that known vibration to see if it is accurate and linear.

Sinusoidal Vibration: A vibration that follows a sine wave pattern, characterized by a single frequency and amplitude.
Frequency Response: A measure of how a sensor's output changes with the frequency of the input vibration.
Transducer: A device that converts one form of energy into another, such as mechanical vibration into an electrical signal.
