accelerometers
Acceleration is measured by a device called an accelerometer, the basic component of which is usually a heavy mass that moves only in one dimension and is supported by springs.

The simplest accelerometer consists of just one weight and has a sliding electrical contact attached to it. As acceleration increases, the weight slips back and a higher voltage is generated; then, as acceleration decreases, the weight moves forward and a lower voltage is generated.
