Meaning and Definition
The measurement of the strength of a gravitational field or the density of rocks and minerals by observing their gravitational effects.
In a broader or historical sense, it can refer to any measurement of weight or mass, though this usage is now archaic. Primarily refers to a geophysical prospecting method or a precise laboratory technique for determining local variations in Earth's gravity.

FAQ
Frequently Asked Questions
Gravimetry measures the static strength of Earth's gravity field to infer subsurface density. Gravitational wave detection (e.g., LIGO) measures ripples in spacetime from catastrophic cosmic events like black hole mergers.
Yes, planetary missions often carry gravimeters. Data from orbiters has been used to map the gravitational fields and infer internal structures of the Moon, Mars, and other celestial bodies.
Yes, satellite gravimetry missions like GRACE and GOCE have mapped Earth's gravity field with high precision, tracking changes in ice sheet mass and groundwater storage.
A gravimeter is the precision instrument used to perform gravimetry. It measures the acceleration due to gravity (g) at a specific location.
The measurement of the strength of a gravitational field or the density of rocks and minerals by observing their gravitational effects.
Gravimetry is usually technical / scientific in register.
Gravimetry: in British English it is pronounced /ɡrəˈvɪm.ə.tri/, and in American English it is pronounced /ɡrəˈvɪm.ə.tri/. Tap the audio buttons above to hear it.

Mnemonic
Think: GRAVity + metRY. You measure (metry) gravity (gravi-).
Conceptual Metaphor
The Earth as a scale (gravimetry 'weighs' the density of underground structures).
