: the gravitational attraction of the mass of the earth, the moon, or a planet for bodies at or near its surface (2) : 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...
Origin ofgravitational force1 First recorded in1690–1710 Discover More Example Sentences The first evidence that dark matter existed is traced back to the 1930s, but it became even more clear that some invisible mass was acting on the gravitational forces of the universe in the 1960s. ...

The Moon’s gravitational pull lifts a tidal bulge in the ocean; as Earth spins on its axis, this bulge remains essentially stationary. As Earth rotates, the tidal bulge runs into the coastlines of continents and islands, causing high tides. The force of the tidal bulge *piling up* against...
