Accelerometer

An accelerometer is a tool that measures changes in gravitational acceleration in the unit it may be installed in. An accelerometer is an electromechanical device that will measure acceleration forces (e.g., G-Force).

An accelerometer is an electromechanical device that will measure acceleration forces (e.g. G-Force). These forces may be static, like the constant force of gravity pulling at your feet, or they could be dynamic - caused by moving or vibrating the accelerometer.
