Absolute gravimeters measure the local gravity in absolute units (Gal after Galileo). KYOWA's strain gage acceleration transducers convert the acceleration of running vehicle or the vibration of car body or machinery into minute voltage to enable accurate measurement of acceleration or vibration with various measuring instruments. Measurement data is stored on an SD card memory and can be transferred directly to a PC via USB or RS-232 interface. If a body is moving with uniform speed in a circular path than its acceleration is called centripetal acceleration because the direction of the motion is changing every moment. So, begin by finding a section of road where you can mark off distance in regular intervals: meters, yards, hundredths of miles, whatever. Device that measures proper acceleration.
