How do they differ from other forces?

There are 4 fundemental forces in nature,\nthe Strong Nuclear force, the Weak nuclear force, Electromagnetic force, and Gravitiy.\n\nThe strong nuclear force has to due how the particles are held together in the nucleus of an atom.  Ordinarily, positively charged protons do not like to be around eachother and neutrally charged neutrons have no reason to be attracted to protons, and yet and the same time, they all are packed very tightly into the atoms nucleus.  The strong nuclear force explain this.\n\nThe weak nuclear force is the force effecting radioactive decay and the active for in the atomic bomb.  Who would have thought that an atomic bomb would represent a "Weak" force.\n\nRead more about the 4 fundemental forces of nature here,\nhttp://hyperphysics.phy-astr.gsu.edu/hbase/forces/funfor.html

is the ques complete is there any friction between the boxes or any other force. can't understand the ques itself do we have a figure somewhere

It is tough because it is so abstract. In Physics one, its all abou force, something you can relate to. In physics II it is more abstract forces like magnetisms and resistence of electricity.  You are not alone.\n\nI found versions of the following books useful to help relate things:\nPhysics For Dummies ® (For Dummies (Math & Science)) by Steve Holzner\n\nComplete Idiot's Guide To Physics (The Complete Idiot's Guide) by Johnnie T. Dennis\n\nPhysics for the Utterly Confused by Robert Oman and Daniel Oman\n\nThese three books take real world examples and show you ho to approach them and relate them in a number of ways. Sometimes it helps to have a source other than the professor and the textbook.

How are they applied? Tangentially? In opposite direction? Or same?\nLet us assume oppo direc and on the border.\nThen net force=35N.\nTorque = r x F = I w\n=35x0.341= ''0.5'' m R^2\nR radius m mass\n ''Check if it is 0.5 only for a solid disk or cyliner about its axis.\n\nHope it helps

its newtons first law, (objects in rest stay at rest unless a force is acted upon it which causes acceleration) and objects in motion stays in motion\n\naka intertia keeps the smaller peices moving in the same direction

They are simply arrows that show the direction a force is applied in (by seeing what direction the arrow points) and how big the force is (magnitude) by how long the arrow is.  So if one vector is twice as long as another, it represents twice the force of the other.

Lift force depends on wing area, angle of attack, air density, airspeed, and several other parameters.  Google "aerodynamic lift" and see.  Happy landing.

1. Diferentiation\n\n2. Outgassing\n\n3. Spring (vernal) equinox\n\n4. This is just presession, the natual motion of a spinning body in a graviational field. not sure what "forces" you are looking for.\n\n5. It marks the equinoxes, the days of the year of even amounts of sun and dark, and we start several of our coordinate systems from the point of the spring equinox.

the force would be determined on how far to the side you are zig zaging. the distance does not matter because it has nothing to do with the force, but with the stamina you have to keep pedaling.

A force is conservative if it can be described as the gradient of a scalar potential. So for instance gravity is conservative because it is proportional to the gradient of the gravitational potential energy.

According to one theory there are particles, which are exchanged and travel between the objects, giving impression that objects attract or repel each other. Nothing is proved yet and it is just a theory, as far as my knowledge is concerned.

You may be right.  The force that they respond to is gravity.  Cold air, being denser, will, in a fluid medium, be drawn closer to the earth, displacing warmer, less dense air.

They are not equal. They variates both over the inverted squared distance, but the gravitational force is F=(m1*m2)/μ*r^2 (F is force, m is pole strength, μ is the permeability of the intervening medium, r is the separation) and the gravitational force is F= -G*(m1*m2)/r^2 (G is the gravitational constant, m1 is the mass of the first object, m2 is the mass of the second object, r is the distance between objects). Indeed, those two forces have similarities in the formula, but they are distinct.

Forces of vander wall I will tell you this in most simple way because that is what I think that you want to know.\nVander Wall forces ( they are forces not bonds, remember always)\nWell those forces are determined by a balance of attraction and repulsion charges between nucleus and atoms.\n\n  One example is this as you know the solar system has planets, they  rotate around the sun and keep distance each another. well\n there are two forces called centrifuge and centripetal, those forces are responsible for the planets to stay in a stable way to rotate without go out of their orbits.\n is the same with the vander wall forces but of course in a molecular level.\n HOW DO WE KNOW ABOUT IT?\nwell those forces have the name of the scientific who discover that behavior in the atomic and molecular world.

Gee .. been a while.  If I remember correctly the magnetic field is perpendicular to the electrical field.  Thus around the two wires the magnetic fields move in the same direction and combine, producing a net attractive force.\n\nIf the currents go the opposite direction, the forces repel.\n\nSee the link below for a more detailed explanation and pictures:

Force=Mass x Acceleration\n\nSo Acceleration = Force/Mass\n\nHope this helps
