gravity
noun1509{ds||2|a|}
- the gravitational attraction of the mass of the earth, the moon, or a planet for bodies at or near its surface
- a fundamental physical force that is responsible for interactions which occur because of mass between particles, between aggregations of matter (such as stars and planets), and between particles (such as photons) and aggregations of matter, that is 10-39 times the strength of the strong force, and that extends over infinite distances but is dominant over macroscopic distances especially between aggregations of matter —called also gravitation, gravitational force
- acceleration of gravity
gravity wave
noun
gravity wave
\
1877{ds||1||}
- a wave in a fluid (such as the ocean or the atmosphere) which is propagated because of the tendency of gravity to maintain a uniform level or in which gravity is the restoring force
- gravitational wave

\
1722
- the acceleration of a body in free fall under the influence of earth's gravity expressed as the rate of increase of velocity per unit of time and assigned the standard value of 980.665 centimeters per second per second —called also g
center of gravity
noun phrase
center of gravity
\
1633{ds||1||}
- center of mass
- the point at which the entire weight of a body may be considered as concentrated so that if supported at this point the body would remain in equilibrium in any position
