Energy shield from the game Second Life. In speculative fiction, a force field, sometimes known as an energy shield, force shield, energy bubble, or deflector shield, is a barrier produced by something like energy, negative energy, dark energy, electromagnetic fields, gravitational fields, electric fields, quantum fields, telekinetic fields, plasma, particles, radiation, solid light, magic, or ...
Force field (chemistry), a set of parameter and equations for use in molecular mechanics simulations Force field (physics) , a vector field indicating the forces exerted by one object on another Force field (technology) , a barrier made up of energy, plasma or particles to protect a person, area or object from attacks or intrusions or as a ...
In physics, a force field is a vector field corresponding with a non-contact force acting on a particle at various positions in space. Specifically, a force field is a vector field F {\displaystyle \mathbf {F} } , where F ( r ) {\displaystyle \mathbf {F} (\mathbf {r} )} is the force that a particle would feel if it were at the position r ...
Electric field from positive to negative charges. Gauss's law describes the relationship between an electric field and electric charges: an electric field points away from positive charges and towards negative charges, and the net outflow of the electric field through a closed surface is proportional to the enclosed charge, including bound charge due to polarization of material.
Representation of the electric field vector of a wave of circularly polarized electromagnetic radiation. The electromagnetic force is the second strongest of the four known fundamental forces and has unlimited range. [17] All other forces, known as non-fundamental forces. [18] (e.g., friction, contact forces) are derived from the four ...
Part of force field of ethane for the C-C stretching bond. In the context of chemistry, molecular physics, physical chemistry, and molecular modelling, a force field is a computational model that is used to describe the forces between atoms (or collections of atoms) within molecules or between molecules as well as in crystals.
In mathematics and physics, the right-hand rule is a convention and a mnemonic, utilized to define the orientation of axes in three-dimensional space and to determine the direction of the cross product of two vectors, as well as to establish the direction of the force on a current-carrying conductor in a magnetic field.
Unification of theories about observable fundamental phenomena of nature is one of the primary goals of physics. [1] [2] [3] The two great unifications to date are Isaac Newton’s unification of gravity and astronomy, and James Clerk Maxwell’s unification of electromagnetism; the latter has been further unified with the concept of electroweak interaction.
