Why are gravitational electromagnetic and nuclear forces often called fundamental or basic forces?
KArLyRoSe
Gravitational, electromagnetic, and the strong and weak nuclear forces are called the fundamental forces because, as far as we have been able to see, all phenomena in the universe can be explained as an expression of one or more of those forces. From a technical standpoint, these are the ONLY forces, but the word 'force' is commonly used when explaining mechanical processes. Therefore, the terms 'fundamental' and 'basic' can also serve to distinguish the use of the word 'force'. Forces like friction, air resistance, and general 'pushing' are all expressions of the electromagnetic force, so they aren't really additional forces. It would be nice if we had a different word for these forces and the 4 fundamental forces to keep things clear, but both uses lay equal claim to the word.
When scientists were studying this. They realized the Electromagnetic and the Weak Nuclear Force were very related, they combined this to form the Electroweak theory. So they suppose they were ALL at one time the same force called Supergravity.
Gravity- Force that pulls to the ground.
Electromagnetic - Combination of Electricity and Magnetics, reason your TV works.
Weak Nuclear Force - Makes Suns energy and Nuclear energy. Also responsible for holding quarks inside the protons and neutrons, Asymptotic Freedom.
Strong Nuclear Force - Holds Protons, Neutrons, and Electrons in the atom.

Why is gravity called a force?
Because it is a force. Gravity is one of the four fundamental forces (gravity, electromagnetism, weak nuclear, strong nuclear or color force).Gravity causes mass to accelerate. F = ma. Gravity must therefore be a force.
Why subatomic particles are called fendamental particles?
Not all of them are; the only direct subatomic part of the atom that is fundamental is the electron (which is a type of lepton.) Only particles made up of no smaller parts are called fundamental particles. For example, the proton (just like the neutron, except with a small difference) is not a fundamental particle because it is made of quarks, which are fundamental particles.
Where did positrons come from?
Where did they come from? They weren't invented they've always been around the positron is a fundamental part of this universe, it is the antiparticle to the electron and is found in many reactions throughout the universe. If you mean how are they created? they can be created in many ways but a common method is a nuclear reaction called a 'Beta Positive Decay' where a Proton decays into a Neutron Positron and neutrino P --> n + e(+) + v
What is the curved orbit called when the earth moves around the sun?
It's called the orbit of the planet. The earth 'orbits' the sun. I don't know the specific name of the line. Maybe the gravitational pull?
What are color forces in terms of quarks the fundamental particles?
The color force is another term for the strong nuclear force. (It doesn't have anything to do with actual colors.) Basically, the color force is the force binding two (or more) quarks together; it's mediated by the exchange of gauge particles called gluons. A quark will change color from, say, "red" to "green" by emitting a red-antigreen gluon, which can be absorbed by a "green" quark (which will then change to "red").
Classification of forces?
There are four major types of force called as universal or fundamental forces of nature. They are: 1. Gravitational Force 2. Electromagnetic Force 3. Strong Nuclear Force 4. Weak Nuclear Force
What types of energy are attributable to each of the four fundamental forces?
The four forces affecting matter are (in order of increasing strength): 1. Gravitational Force : hydraulic energy or water falls 2. Electromagnetic Force : electricity as secondary energy 3. Weak Nuclear Force: ionizing radiation4. Strong Nuclear Force: nuclear fissionWhenever there is a force, or more precisely a so-called "conservative force", there is an associated potential energy. Each of the fundamental forces have related potential energy; thus, there is gravitational, electrical & magnetical, and nuclear potential energy.I am not entirely sure about the weak force; but I assume it would be lumped together with the strong force, in the category of "nuclear energy".Chemical energy, as well as elastic energy, are also types of potential energy that are related to electrical forces.
What are all the forces used in physics?
The entirety of forces used in Physics is long and strenuous, but the forces from which these deviate from are called the Four Fundamental Forces or Interactions These are; The Strong Nuclear Interaction which binds nuclei and quarks together, the The Weak Nuclear Interaction which is responsible for radiation, The Electromagnetic Force which is, obviously, responsible electricity and magnetism, and Gravitation
What is free space?
A area that has no gravitational and electromagnetic fields, used as an absolute standard, Also called emptiness (no longer in technical usage).
Why are atoms charged particles?
As stated the question is a tautology. Charged atomic particles are charged because you just said they were charged."Atomic particles" is a little vague. I assume you mean "subatomic particles". Some of these are charged, and others aren't. For the fundamental particles, there's no known reason they have a charge (or not), they just do.In addition to the electromagnetic charge (which is probably what you meant when you said "charged"), physicists need to consider a different kind of charge, which is variously called the strong nuclear or color charge. I think "color charge" is a fun phrase, so that's what I'll call it.Electrons have an electromagnetic charge, but no color charge.Photons have no charge.Quarks have both a color charge and electromagnetic charge.Gluons have a color charge, but no electromagnetic charge.Those are fundamental particles, so the reason they have or don't have those charges is "because that's the way things are."Protons are made of quarks (with electromagnetic and color charges) and gluons (with color charges). The color charges cancel out, so protons have no overall color charge, but the electromagnetic ones don't, so they wind up with an electromagnetic charge.Neutrons are also made of quarks and gluons. However, in neutrons, both the color and electromagnetic charges cancel out, so neutrons have no overall electromagnetic charge and no overall color charge.(Technically, there's also "gravitational charge," which is a measure of how much the particles interact with a gravitational field. However, everything, even photons, has a gravitational charge, so that's kind of boring.)
Why nuclear reactions are more explosive?
Nuclear reactions are more "explosive", i.e. energetic, because they depend on the release of binding energy, which is also called the strong force, or the strong interaction. (The four fundamental forces in nature are the strong force, the electromagnetic force, the weak force, and gravity.) Contrast this with chemical reactions, such as the detonation of TNT, and you have many, many more orders of magnitude per unit of source mass with nuclear.
The electromagnetic force is the force that holds nuclei together true or false?
The force between nucleons is called nuclear force.
Electricity is one of two aspects of which fundamental force?
The force that includes both electricity and magnetism is called the electromagnetic force.
Which 2 of the universal forces work inside an atom's nucleus?
The 2 forces are-Strong nuclear force: The strong nuclear force or strong interaction (also called color force or colour force) is a fundamental of nature which affects only quarks and antiquarks, and is mediated by gluons in a similar fashion to how the electromagnetic force is mediated by photons. This force is responsible for binding quarks together to form hardons (including protons and neutrons), and the residual effects also bind these neutrons and protons together in the nucleas of the atom.Weak nuclear force: A force which is responsible for all of the byproducts of nuclear interactions. It is the only mechanism which can convert nuclear binding energies into electromagnetic energy, and hence heat and mechanical energy
What is the nuclear force of attraction?
The strong nuclear force, also called binding energy, holds quarks together to form protons and neutrons. Residual binding energy, also called the nuclear force, holds protons and neutrons together to form the nucleus of an atom. This holds true up to about atomic number 83 (bismuth), at which point the electromagnetic force, a repulsive force for protons, starts to overcome the distance barrier of binding energy and make the nucleus unstable. This makes the atoms starting at bismuth and above be radioactive. Additionally, the presence or absence of extra neutrons, i.e. isotopes, even in light nuclides, can, due to the weak interaction, makes the nucleus be unstable, and radioactive.
What is the arrangement of electromagnetic waves according to their wavelengths and frequencies called?
That's called the electromagnetic spectrum.
Energy that is transferred by electromagnetic waves is called electromagnetic what?
Energy transferred by electromagnetic waves is called radiation.
