The phrase "a decrease in gravity" is correct and usable in written English.
It can be used in contexts discussing changes in gravitational force, such as in physics or science fiction scenarios.
Example: "The experiment resulted in a decrease in gravity, allowing the objects to float freely in the chamber."
Alternatives: "a reduction in gravitational force" or "a decline in gravity".
This goes along with a decrease in minimum gravity from about −4.5 mgal in the 30-km filter (AN1a) to < −18 mgal in the 120-km filter (AN1) and an extension of the entire anomaly towards the east.
This result was supported by a change in the physical properties related to the size of free volumes, such as a decrease in the specific gravity, a decrease in the dielectric constant and an increase in the water pick-up rate with increasing the decree of the cure.
A decrease in tablet-specific gravity causes the tablet to float on extended residence time in the stomach, improving absorption.
Since unrest periods are accompanied by increases of the ({mathrm{CO}}_{2}/{mathrm{H}}_{2}{mathrm{O}}) ratio, a decrease in the ratio between gravity and vertical deformation could help in detecting the onset of unrest phases.
Scores on mCTSIB measures also demonstrated improvement represented by a decrease in the mean center of gravity (COG) sway velocity.
A decrease in porosity yielded in-lab specific gravities that converged.
Together, metabolic data revealed that exposure to increased gravity load caused a decrease in the capacity to oxidize glucose or incorporate glucose into lipid in all three tissues during lactation.
Ca(OH 2 within the adhered mortar is converted to CaCO3 by carbonation, and the porosity of the adhered mortar decreases, leading to an increase in the specific gravity of aggregates and a decrease in its absorption rate (Ryou and Lee 2014; Ondova and Sicakova 2016).
After a 14-day simulation of gravity discharge, there was a decrease in connexin 43 (gap junction intercellular protein) content in rat myocardium [ 23].
