In which direction does the X Accelerometer measure motion?

The X accelerometer typically measures motion along the East-West axis. In a three-dimensional coordinate system used for accelerometers, the X-axis is designated to capture lateral movements, while the Y-axis usually corresponds to the North-South orientation, and the Z-axis represents vertical motion. Therefore, when considering the specific orientation of the accelerometer, the correct answer identifies the function of the X-axis accurately by indicating that it tracks movements in the East-West direction. This understanding is crucial for interpreting data from accelerometers in various applications, such as navigation, motion tracking, and robotics, where accurate measurement of lateral movements is essential for system performance.
