Sentences with phrase «gravity measurements»
Gravity measurements refer to the process of studying and analyzing the force of gravity in a particular area or region. It involves collecting data and using instruments to measure and understand the strength and variations of gravity. This can help scientists understand the composition of the Earth, locate underground resources like oil or minerals, and study the dynamics of oceans and tides. Full definition
