What is a field?
- In physics, a field is a physical quantity, represented by a number or another tensor, that has a value for each point in space and time.
- Field, In physics, a region in which each point is affected by a force. ... An electric field surrounds an electric charge; when another charged particle is placed in that region, it experiences an electric force that either attracts or repels it.
- Some of the fields in modern physics are: Astrophysics: The study of the physical properties of objects in space. Today, astrophysics is often used interchangeably with astronomy and many astronomers have physics degrees.
- 24 fields -- (Standard Model including all colors and gluons ) — 12 fermion fields and 12 boson fields.
- In physics, a force field is a vector field that describes a non-contact force acting on a particle at various positions in space. Specifically, a force field is a vector field , where is the force that a particle would feel if it were at the point .
