Inertial Measurements Linear Acceleration: accelorometers

are sensors that can detect the relative linear acceleration along an axis. The basic principle of operation can be thought of as an object suspended on a spring. When the system is acelerated along the spring direction, the mass moves, relative to the spring mounting point. The displacement of the object is proportional to the spring constant, its mass, and the acceleration. Only measure acceleration component along one dimension. Often implemented as MEMS
