Which of the following is the BEST definition of what an accelerometer does?

The correct answer is C. Measures velocity in a given direction. An accelerometer is a sensor that detects and measures acceleration forces (changes in velocity) along one or more axes. In smartphones and mobile devices, it is used to detect orientation, movement, and motion - such as rotating the screen or tracking steps. It does not…

Explanation

An accelerometer is a sensor that detects and measures acceleration forces (changes in velocity) along one or more axes. In smartphones and mobile devices, it is used to detect orientation, movement, and motion - such as rotating the screen or tracking steps. It does not prolong battery life, calculate rotation (that is a gyroscope's function), or increase device processing speed. The closest accurate description among the choices is that it measures velocity/movement in a given direction.
