ac·cel·er·om·e·ter

(ak-sel-er-om'ĕ-ter),
An instrument for measuring the rate of change of velocity per unit of time.

accelerometer

Any instrument used to measure acceleration.

Typically, accelerometers contain a small mass, connected to a stiff spring, with some electrical means of measuring the spring deflection when the mass is accelerated; the type of accelerometer used in gait analysis is usually very small and measures acceleration in one direction, but can be clustered for two- and three-dimensional measurements.

accelerometer

(ak″sel-ĕ-rom′ĕ-tĕr) [ acceler(ation) + -meter]
An instrument that detects a change in the velocity of the object to which it is attached. The device may be designed to record the changes and indicate the direction(s) of the acceleration.
