![]() ![]() ![]() The elongation of the spring under the force exerting on the mass gives a measure of the acceleration proper acting on the system or the frame. In general, the structure of an accelerometer has a mass connected to a spring (or two). Simply put, the accelerometer measures the g-force acceleration of the object or the frame. An accelerometer displays an acceleration of 9.83ms-2 on earth, zero in free fall and space, when at rest. It does not necessarily measure the rate of change of velocity in that frame, but the acceleration experienced by the body or frame. the physical acceleration experienced by an object. The accelerometer is a device used to measure the proper acceleration i.e. Combining the information obtained from the two devices, the motion of an object in the 3-d space can be calculated and projected to a high degree of accuracy. Their operation is based on the concept of inertia, which is the reluctance by masses to change its state of motion, hence called inertial measurement units in engineering applications.Īccelerometer, as the name implies, is used to measure the linear acceleration, and gyroscopes are used to measure various rotational movement parameters. The Accelerometer and gyroscope are two motion sensing devices commonly used in modern technological equipment.
