مقياس التسارع المعرفة
مقياس التسارع accelerometer، هو جهاز لقياس التسارع الحقيقي للجهاز. This is not necessarily the same as the coordinate acceleration (change of velocity of the device in space), but is rather the type of acceleration associated with the phenomenon of weight experienced by a test mass that resides in the frame of reference of the accelerometer device.
