Question 10
An accelerometer is a device to measure acceleration. At the earth sea level, the acceleration due to gravity is g = 9.8 m s⁻². Most of the smartphones such as Android and Apple iPhone consist of a builtin accelerometer. If a smartphone is moving vertically upward at sea level with constant velocity 9.8 m s⁻¹, the instantaneous scalar readings of the x, y, and z components from the accelerometer are:
