Define the term (force) field and apply this to the definition of:
Gravitational fields
Magnetic Fields
Answers
Answer:
a gravitational field is a model used to explain the influence that a massive body extends into the space around itself, producing a force on another massive body.[1] Thus, a gravitational field is used to explain gravitational phenomena, and is measured in newtons per kilogram (N/kg). In its original concept, gravity was a force between point masses. Following Isaac Newton, Pierre-Simon Laplace attempted to model gravity as some kind of radiation field or fluid, and since the 19th century explanations for gravity have usually been taught in terms of a field model, rather than a point attraction.
Magnetic field | Definition of Magnetic field at Dictionary.com A field of force associated with changing electric fields, as when electric charges are in motion. Magnetic fields exert deflective forces on moving electric charges.

Answer:
Force is the influence that produces a change in a physical quantity.
Explanation:
Gravitational field
The gravitational field is the space around a mass or an assembly of masses within which it can exert gravitational forces on other masses.
Theoretically speaking, the gravitational field extends upto infinity . However, in actual practice , the gravitational field may become too weak to be measured beyond a particular distance.
Si unit of gravitational field Newton/kilogram (N/kg).
Magnetic field
A region of space near a magnet , electric current or moving charged particle in which magnetic effects are exerted on any other magnet , electric current or moving charged particle.
It is also called as magnetic flux density or magnetic induction or magnetic field.
Si unit of magnetic field is Weber/(meter)^2 or Tesla (T).
