A spring is a device consisting of an elastic but largely rigid material bent or molded into a form that can return into shape after being compressed, extended or twisted. Springs can store energy whe
Gravimetry
…Thus, gravimeters can be regarded as special-purpose accelerometers. Many weighing scales may be regarded as simple gravimeters. In one common form, a spring is used to counteract the force of gravity pulling on an object. The change in length of the spring may be calibrated to the force required to balance…
