A very simple and not particularly scientific definition of the physical, or proper, acceleration of an object is how fast it gains velocity compared to an object standing still. The accelerometer is the tool used to measure this gain in velocity. It is used throughout many industries for innovative solutions to difficult problems.

The surprising number of uses do not all pertain to Einstein or to bodies in space. Different types of components are used in conjunction with it to translate what is essentially a mechanical motion into an electrical signal so it can be displayed. The device itself does not typically display any information; it only makes the results of the measurement available for other products to interpret.

It is used to measure the acceleration of cars to allow a very specific evaluation of the engine, in conjunction with the drive train. Engine performance is an important factor in the automobile industry. The ability to have a reliable measurement of multiple products, or the same product in different phases is helpful in improving engineering. Automobile braking systems are the foundation of car safety claims. Accurately measuring the ability to stop quickly has serious implications for the safety of a car.

When used to measure vibrations, the device can warn users of the first rumblings of an earthquake. Active volcanoes always have magma, but when it begins to vibrate as it moves toward the surface, the possibility of an eruption increases. By accurately measuring the movement of the magma, many lives can be saved as the area is evacuated sooner. Even marine biologists are making use of these products to determine the activities of animals in the wild and how much energy they are using. While it is mostly used for marine animals, it is also being used for animals on the surface of the earth.

One of the main reasons that machinery of any kind breaks down is that the parts begin to vibrate and wear unevenly. When a certain point is reached, the equipment stops working. This can be simply an inconvenience, or in the case of large equipment, it can be dangerous to employees. From paper mills to oil fields, determining a potential problem with machinery saves not only time and money, but also human lives.

The measurement of dynamic loads is when the motion and vibration of a structure are measured when weight is added to it. The process of measuring dynamic loads is called dynamic monitoring. An example is moving a heavy truck across a bridge and monitoring the motion and vibration of the bridge as the weight is added. If the readings show severe stress, the load can be taken off the bridge without damage. This should not be confused with the computer-related term, dynamic loading. This is a method used to load libraries of information when programs are run.

Some surprising new products make use of accelerometers. Computer games that mimic human movements are using this device. As the user moves, the computer screen moves the avatar. Exercise equipment is available that measures steps, the force of impact, distance and speed.

Even taking pictures with a cell phone or camcorder uses an accelerometer. As the camera is adjusted to photograph the subject, it stabilizes the image.
