Tidal force

The tidal force or tide-generating force is the difference in gravitational attraction between different points in a gravitational field. It causes different parts of bodies to be pulled unevenly, so

…apart by gravitational forces. He described a method of calculating the distance at which an object held together only by gravity would break up due to tidal forces; this distance became known as the Roche limit. His other best known works also involved orbital mechanics. The Roche sphere describes the limits at…
