Final answer:
Accelerometers are passive devices that measure the acceleration of an aircraft component in the form of a voltage signal. Acceleration is a measure of how fast the velocity of an object changes in time. The accelerometer detects changes in acceleration and converts them into a voltage signal.
Step-by-step explanation:
Accelerometers are passive devices that measure the acceleration of a selected aircraft component in the form of a voltage signal. Acceleration is a measure of how fast the velocity of an object changes in time. It can be represented as a or by its magnitude.
In this case, it is measured as a voltage signal by the accelerometer. Example: If an aircraft is experiencing a sudden increase in acceleration, the accelerometer will detect this change and produce a corresponding change in voltage signal.
