# What is gravitational force?

• (noun): (physics) the force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface.
Synonyms: gravity, gravitation, gravitational attraction

... in 1742 he shortened the related passages and ascribed "perfect elasticity or spring force" to the particles and on the other hand "imperfect ... would lead to a steady decrease of the particle speed and therefore a decrease of the gravitational force ... in densities) can be made arbitrarily small while still maintaining the same effective gravitational force ...
Shell Theorem
... In classical mechanics, the shell theorem gives gravitational simplifications that can be applied to objects inside or outside a spherically symmetrical body ... a hollow ball), no net gravitational force is exerted by the shell on any object inside, regardless of the object's location within the shell ... A corollary is that inside a solid sphere of constant density the gravitational force varies linearly with distance from the centre, becoming zero by symmetry at the centre of mass ...

Thus, the tidal force depends not on the strength of the lunar gravitational field, but on its gradient (which falls off approximately as the inverse cube of ... The solar gravitational force on the Earth is on average 179 times stronger than the lunar, but because the sun is on average 389 times farther from the Earth, its field gradient is weaker ...

The affirmative class monopolize the homage of mankind. They originate and execute all the great feats. What a force was coiled up in the skull of Napoleon!
