Accelerometer
Instrument used to measure the acceleration of a vessel, which is the direction and amount of velocity change. It can also measure inclination, vibration, and shock. This instrument is apart of a starship’s inertial guidance system.
Since the effects of gravity and acceleration are indistinguishable as they act upon a body, the output of an accelerometer has to be offset to compensate for this local gravity. This means when a starship approaches a body that acts as a force of gravity (such as a star, a planet or moon, or during atmospheric flight), the accelerometer will take the gravity into consideration and display both the ships acceleration with an without the effect of the gravity acting on the ship.
During warp, acceleration is measured in light years/second^2. During impulse, it is measured in meters/second^2.
The origins of this technology dates back to the 20th century and was found in portable electronic devices, personal computers, automobile airbags, and early spacecraft.
