Balways attractive Cattractive only at large distances Drepulsive only at large distances.Submit Assertion : Gravitational force between two masses in air is F. If they are immersed in water, force will remain F Reason : Gravitational force does not depend on the medium between the masses. AI...
Electrostatic force can be described as the Coulomb force or Coulomb interaction, and it is the attractive or repulsive force between two electrically charged objects. Gravitational force can be described as the force that acts on an object due to gravity. The key difference between electrostatic fo...
Is the weak nuclear force attractive or repulsive? Is the weak nuclear force stronger than the electromagnetic force? How do we sense the weak nuclear force? Is the strong nuclear force the strongest force? What does the weak nuclear force do?

The fields transfer attractive or repulsive action between parti- cles, and gravitation is not seen as an attractive force in gen- eral relativity, but as a consequence of the coupling between mass and the curvature of space-time. I compare this to a billiard game (although in this analogy,...
Exist between moving or stationaryelectrical charges Can be an attractive or repulsive force Nuclear Force/ Strong Force Forces between protons and neutrons and other sub-nuclear particles when they are close together Holds the atomic nucleus together as it keeps the protons together in the nucleus,...
“dark energy” makes the expansion of the universe accelerate. Dark energy has the equation of statep=–ρ, which, when plugged into the equation, givesR00=–2ρ. This is negative, meaning, heuristically, that dark energy causes “repulsive gravity” instead of “attractive gravity”; a ...
attactive and repulsive gravityA general line element and a general metric tensor are defined as functions of two parameters α and α'. The related Einstein's field equations of a gravitational potential field in a vacuum, including parameter Λ, have been derived. The parameters α and α' ...
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 ...
The strong force or strong nuclear force is one of thefour fundamental forcesof nature, along withgravity,electromagnetismand the weak force. As the name suggests, the strong force is thestrongestforce of the four. It binds fundamental particles of matter, known as quarks, to form larger partic...
