- Action at a distance - Wikipedia
By 1785 Charles-Augustin de Coulomb showed that two electric charges at rest experience a force inversely proportional to the square of the distance between them, a result now called Coulomb's law
- Physics Tutorial: Action at a Distance
Gravitational forces are action-at-a-distance forces that act between two objects even when they are held some distance apart If you watch a roller coaster car move along its course, then you are witnessing an action-at-a-distance
- 8. 3 Forces at a Distance - OpenSciEd
Forces that act at a distance (electrical, magnetic, and gravitational) can be explained by fields that extend through space and can be mapped by their effect on a test object (a charged object, a magnet, or a ball, respectively)
- Action at a distance Definition - Principles of Physics I Key Term . . .
Newton's Law of Universal Gravitation illustrates action at a distance by stating that every mass exerts an attractive force on every other mass without any physical contact
- Fields (video) | Forces | Khan Academy
So while fields may sound mysterious, they really just mean that a force is felt over a distance Gravitational, electric, and magnetic forces are all field forces, which means they act over distance and can affect a lot of objects

All forces act at a distance This is obvious for the gravitational force Earth and the Moon, for example, interact without coming into contact It is
- Action at a Distance - University of Oregon
A conceptual difficulty in Newtonian mechanics, however, is the way in which the gravitational force between two massive objects acts over a distance across empty space or in electromagnetism how a magnetic force operates between two charged particles

These forces are short-range and operate at distances smaller than an atomic nucleus The strong nuclear force holds protons and neutrons together in the nucleus The weak nuclear force governs radioactive decay and neutrino interactions
