What is field in physic?

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. This has led physicists to consider electromagnetic fields to be a physical entity, making the field concept a supporting paradigm of the edifice of modern physics.

What is the field force?

A field force is described with the help of a vector quantity which determines the magnitude and direction of this force in the field at any point. All the field forces are non-contact in nature. There are two fundamental field forces in nature, the Gravitational force and the Electromagnetic force.

What is Field Force answer?

Answer: 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.

What is a field force answer?

Does force field exist?

Because force fields can act as a barrier to the external world, it would be possible to have homes built in locations as unrelenting as the ocean depths. Of the four forces of the universe — gravity, electromagnetism, and the strong and weak nuclear force — none seem to allow for the existence of a force field.

What are agricultural fields?

An agricultural field can be defined as a field that is used for growing crops or other high-value plant species. Normally, only a single plant species is grown in an agricultural field at any particular time, and additional management activities are practiced to suppress the growth of weeds and pests.

What is the difference between a magnetic field and electric field?

(Because its interior acts like a magnet, the Earth is surrounded by a magnetic field that affects things made of magnetic material, such as compasses). A charged object is surrounded by an electric field which exerts electrical forces on other things within the field.

What are the different types of forces in physics?

Or to read about an individual force, click on its name from the list below. 1 Applied Force. 2 Gravitational Force. 3 Normal Force. 4 Frictional Force. 5 Air Resistance Force. 6 Tension Force. 7 Spring Force.

What are the most fundamental things in physics that you don’t understand?

As such, one of the most fundamental things in physics that I still don’t understand (a year after dropping out from the university) is the concept of field. No one cared to explain what a field actually is, they just used to throw in a bunch of formulas and everyone was content.

What are some real life examples of force acting on objects?

Gravity as well as electrostatic and magnetic attraction and repulsion provide real life examples of forces being exerted by one object on another without them being in contact with each other.
