Acceleration is defined as rate of change of velocity with respect to time. A Accelerometer is an instrument for measuring acceleration, typically that of an automobile, ship, aircraft, or spacecraft, or that involved in the vibration of a machine, building, or other structure. Proper acceleration is the acceleration (the rate of change of velocity) of a body in its own instantaneous rest frame; this is different from coordinate acceleration, which is acceleration in a fixed coordinate system.For example, an accelerometer at rest on the surface of the Earth will measure an acceleration due to Earth's . This is the sensor onsensorchanged implementation (very simple I think) but not working. The Applications of Accelerometer sensor are as follows: For inertial navigation systems, highly sensitive accelerometers are used. Depending on how long it is since you had to deal with the physical properties of objects, you may recall that the SI unit of acceleration is m/s² . The force caused by vibration or a change in motion (acceleration) causes the mass to "squeeze" the piezoelectric material which produces an electrical charge that is proportional to the force exerted upon it.
