WebMay 19, 2024 · There are two types of gravimeters: absolute and relative. Absolute gravimeters measure gravity by looking at the acceleration of an object in free fall over a set distance. For example, a cold atom gravimeter measures gravity by calculating the acceleration of falling atoms that have been cooled to near absolute zero temperature.
