Electricity is the flow of electrons through a conductor.Movement of electrons.The voltage is the pressure that push the electrons through a conductor.When you throw a ball your hand is the voltage because is the force that push the ball,the ball is the ''electricity'' and the wind is the resistance.

This is a simple application of Coulomb's Law.\nThe Electric Field is simply given by the charge on the nucleus (26e) divided by 4*Pi*EpsilonNought*distance^2\nWhere e is 1.6*10^-19 Coulombs

well, if an object is moving, there must be some physical force applied to it - magnetic field, static electicity, pull from a sting, air pressure from a fan.

All molecules are experience London Dispersion, or induced dipole-induced dipole forces.\n\nConsider He.  When both electons in the electron cloud are spontaneously bear one another, this causes a partial negative charge on one side of the atom and a partial positive charge on the other side.  This 'dipole' can then induce a dipole moment on another He atom.  London dispersion forces are relatively weak and exponentially dependent on the distance between atoms- so they must be relatively close to one another.

One of the four forces in nature is the electromagnetic force.  A sub-aspect of this is the qualities of electromagnetic radiation.  What is electromagnetic radiation?  It's every form of energy radiation on the electromagnetic spectrum such as:\nmicrowaves -- get a quick meal, transmit information using microwaves as a carrier wave like cell phones and satellites do.\nradio waves -- pretty much everyone knows what a radio is and has one.\nX-rays -- medical diagnosis would be lost without them.\nUse of the magnetic force also allows for things in the medical industry such as MRI and CT scans....that whole nuclear medicine field.\nThe flow or movement of particles called electrons is studied by physicists.  The flow or current of electrons is also known as electricity.  Lots of people use that for various things.\nIn a fundamental sense, everything is made up of atoms.  \nThe atomic and sub atomic world is the purview of the field of study called quantum physics.  So, EVERYTHING is influenced by physics in a sense.

Strickly speaking there are four fundamental forces: electromagnetic, gravity, the strong nuclear, and the weak nuclear force.\n\nOn the other hand, it has been shown that the electromagnetic and weak forces are two aspects of the same thing - sort of like how ice and water are two aspects of the same thing. And it has been shown that this electroweak force is the same as the strong nuclear force.\n\nIn other words, those three forces are really one force that we observe as different aspects.\n\nGravity has yet to be connected. String theories are one way being pursued to try and link all four forces together. I ten to think, and most physics people do, that gravity is related. \n\nBut if it isn't then we have : electroweak-strong and gravity as the two forces.

There is a symbol for magnetic fields, which is B and has the unit Tesla.  \n\nGenerally, all forces are represented by F, and you just specify the context in which the force takes place.\n\nFor example:\n\nA charged particle moving through a magnetic field experiences a magnetic force given by:\n\nF = qv X B\n\nWhich is the charge, q, times its velocity v, in a cross product with the magnetic field.  \n\nAlso, there is a an equation for magnetic force between two magnetics that is similar to that of gravity and electricity:\n\nF = Km1m2/r^2\n\nWhere K is the constant, m one and m two are called magnetic moments, and r is the distance between them.  Still, the symbol for the force is just F.

The electric field will be repellent between protons, attractive between a proton and an electron.\n\nThere is, of course, the nuclear force--which is exerted only at extremely close range, and is an attractive force.\n\nThere is also the gravitational force between them, also attractive, but it's pretty trivial with such microscopic masses, unless you get unthinkably close.\n\nGravity, of course, would be there between the proton and the electron, but it's a whale of a lot more feeble between that pair than between a pair of protons...

Ancient\nAccording to Thales of Miletus, writing at around 600 BC, a form of electricity was known to the Ancient Greeks who found that rubbing fur on various substances, such as amber, would cause a particular attraction between the two. The Greeks noted that the amber buttons could attract light objects such as hair and that if they rubbed the amber for long enough they could even get a spark to jump.\n\nAn object found in Iraq in 1938, dated to about 250 BC and called the Baghdad Battery, resembles a galvanic cell and is believed by some to have been used for electroplating.\n\n[edit]\nModern\n \nLeyden jars, Museum Boerhaave, Leiden [3].Italian physician Girolamo Cardano returned to the subject of electricity in De Subtilitate (1550)[1], distinguishing, perhaps for the first time, between electrical and magnetic forces. In 1600 the English scientist William Gilbert, in De Magnete, expanded on Cardano's work and coined the modern Latin word electricus from ηλεκτρον (elektron), the Greek word for "amber", which soon gave rise to the English words electric and electricity.\n\nHe was followed in 1660 by Otto von Guericke, who invented an early electrostatic generator. Other European pioneers were Robert Boyle, who in 1675 stated that electric attraction and repulsion can act across a vacuum; Stephen Gray, who in 1729 classified materials as conductors and insulators; and C. F. Du Fay, who first identified the two types of electricity that would later be called positive and negative.

In physics, the Lorentz force is the force exerted on a charged particle in an electromagnetic field. The particle will experience a force due to electric field of qE, and due to the magnetic field qv × B. Combined they give the Lorentz force equation (or law):\n\n F= q(E + v x B)\nwhere\n\nF is the force (in newtons) \nE is the electric field (in volts per meter) \nB is the magnetic field (in webers per square meter, or equivalently, teslas) \nq is the electric charge of the particle (in coulombs) \nv is the instantaneous velocity of the particle (in meters per second) \nand × is the cross product. \nThus a positively charged particle will be accelerated in the same linear orientation as the E field, but will curve perpendicularly to the B field according to the right-hand rule.

Putting it simply:\nEffort force, is force that must be applied to do something,eg, to push a block.\nResistance force, is the force which restricts the movement,eg, the friction of the block with the ground.

We know of four types of fources, gravitational, electromagnetic, strong and weak forces. gravitational force will be there whereever massive bodies are present. If electrically charged bodies are present then electromagnetic force will also be there. Strong nuclear and weak forces are also likely to be there between subnuclear particles. So I guess all four forces will be present at the planets you mention.

Gravity is the basic force. There is also a positive feedback effect; the more massive a cluster becomes, the more strongly it draws other particles and clusters toward it.

Protons are positively charged particles.\n\nBetween protons there are two types of forces.\n\nOne is the electro-static repulsion between two protons.\n\nThe other is the gravitational force of attraction between the masses of protons.\n\nWhen two protons are separated by any distance,\n\nThe electro-static repulsive force is 1.29 x 10^28 times greater than the gravitational attraction between them.
