Application to endurance running. From Wikibooks, open books for an open world. Background George Atwood invented the very first accelerometer in the s. The Atwood machine, as it was called, consists of masses on springs where the velocity is calculated based on displacements experienced. Over the years, technology has evolved to the use of resistance-bridge type accelerometers in the early s, followed by the use of piezoelectric accelerometers commonly used today Walter, More on the mechanism can be found here.

There was little need for the Atwood accelerometer until the rise of the automobile industry. As demand increased, automakers found it necessary to make their vehicles safer and more efficient. By placing many accelerometers in a test vehicle, researchers are able to determine where the engine's power is being dispersed. Simple forward acceleration can be measured, of course, but so can the sideways and up-and-down shiftings within the car's frame.
Automotive researchers often place a human-sized dummy containing several accelerometers inside a moving vehicle in order to determine the effect of the car's motion upon a passenger.
