These lines show us that an "attractive" or "repulsive" force can act at a distance within a portion of space called a "field." Fields carry the energy of everything that exists in the universe, from atoms to large galactic structures. Magnetism, gravitation, nuclear force, light, and ...
As shown in the picture above, an object resting on a table will experience acontact force(or known asnormal force) acting on it in the upward direction. Notice that the box is at rest. FromNewton’s First Law of Motion(you will learn about this law in the subsequent sub-topics), you...

Quantum vacuums give rise to the attractive Casimir force, but could we convert this into something that is repulsive instead? Sort of. Research by scientists at the University of California at Berkley and Hong Kong University has found a way to balance out the attractive force with a repulsive...
The strong force or strong nuclear force is one of the four fundamental forces of nature, along with gravity, electromagnetism and the weak force. As the name suggests, the strong force is the strongest force of the four. It binds fundamental particles of matter, known as quarks, to form ...

The other three forces are attractive forces, electromagnetic being attractive and repulsive. The weak force appears on the surface to be more of an intermediary particle than a force. What is the force? Is it quantum jitters or something else? edward says: February 21, 2013 at 10:...
Coupling electrodynamics with gravity introduces the geometry of De Sitter spaces [66,67], which provides attractive/repulsive forces dependent on distance from the origin and can distinguish between Schwarzschild and De Sitter black holes, ensuring the electron’s stability from the Coulomb repulsion. ...
A quantum actualization enhancement of repulsive Casimir effect would be anti-gravitational and of possible practical use. The ideas and concepts discussed here are not yet a theory, but at most the start of a framework that may be useful. Keywords: quantum gravity; non-locality; General ...
Gravity is not an attractive force. Gravity is the atomic consumption of spacial void. This happens at the speed of light, c. As you sit where you are, stuck to this planet, you do so because space rushes through you toward earth's center of mass. Being on the earth's surface, the...
