Generating force from nothingIf we have two opposite equal forces that affects an object so that the forces does not make displacement , i.e. No work is done then the forces can increase continuously without limit and without any external force just by itself and from nothing!! This is the concept of generating force from nothing. Proof:This experiment shows that the above concept is true, it uses the idea of canceling one force of the two mutual attraction forces between magnets : 1, 2 , 3 ,4 are identical magnets, 5 is an spring , that conserve energy ,the distance between magnets 1 and 2 equals distance between magnets 3 and 4 , magnets 1 and 3 are connected together using brown bar, the brown bar goes inside magnet 2 with little friction.So as a result of this the two magnets 1 and 3 can move toward magnet 4 with little force , if we consider there is little friction forces , because the repel force between magnet 1 and 2 cancel the attraction force between magnet 3 and 4 since the four magnets are identical and the distances are equal . But!! What about magnet 4 its attraction force increases AND ALSO DECREASES while we move the two magnets 1 and 2 from left to right, there should be change in force , while we do exert little external force to the system.Conclusion:The force exerted by magnet 4 on the lower grey surface and the upper grey surface increases with exerting little external force. also can be decreased without external forces , as a result of the coming back of the spring This a proof of the above concept of generating force from nothing.

.....suppose the car moved towards the other surface with very little force (no friction) and the car moved totally from the first surface to the second one, now this contradict you said no force can act on a body if there is not something cause the force to begin, the force acted on the second surface by moving the car with force tend to zero.
yes , I did so, just refer to what pmbphy said and what I said to see why I presented this example.
also I increased stress on surface 2 with force tend to zero by collecting more cars, just refer to what I wrote.
Quote from: PmbPhy on 19/05/2015 06:16:26Wrong. You can't have a force acting on a body if there's nothing to cause the force to begin with. yes I can. this example will illustrate that I am right an you are wrong :imagine that there are two surfaces which are perfectly horizontal , they are also identical and they are exactly at the same height ,one surface is very close to the other however they are distinct they don't touch, now there is a car on the first surface this car has a particular weight W and the first surface exerts a normal force on it equals W , there is not any forces on the other surface , however suppose the car moved towards the other surface with very little force (no friction) and the car moved totally from the first surface to the second one, now this contradict you said no force can act on a body if there is not something cause the force to begin, the force acted on the second surface by moving the car with force tend to zero. also we can increase the normal force on surface 2 by collecting other cars!! moving those other cars with forces tend to zero , also review my above experiment it also shows this. Quote from: PmbPhy on 19/05/2015 06:16:26The example in no way shows that the above is true. That's something you have to prove. You can't assume it. By the way. Where did these magnets come from? You didn't mention them before your proof and didn't explain what role they play in your proof. the example uses magnets but I wanted to extract from the example the concept. force is force whether it is magnetic or electric etc , if we have magnetic force increases without external force then we can have other forces to have the same feature.
Wrong. You can't have a force acting on a body if there's nothing to cause the force to begin with.

Quote from: Thebox on 19/05/2015 18:04:19A force is a product of process and not a thing itself. That is why you can not produce a force from nothing. quite simple physics really.yes a force is a factor that affects object ,I agree with basic physics but I do not agree with your logic that force is not a thing by itself so it can't be produced from nothing, I want to ask you something , how a force acts between two objects that have distance between them? it seems that while a force is not a thing by itself then it needs some kind of connector to do its job , in other words force needs matter to transfer it to other objects , I who is a person will be able to produce force and increase it and decreased because I am a thing , also the effect of gravitational force is every where in the universe , also it increases and decreases according to places in vacuum not according a person who is a thing to do the job , generating force from nothing means in creasing it or decreasing without an external factor , but this something noticeable in universe gravity increases or decreases every where without the thing you mentioned , all I did is increasing it in field without doing work ,but that is just according to your interpretation for " a force is not a thing by itself" , the true interpretation is : force is not a thing by itself it needs something to act on to appear, if there is something exists to act on then it can be measured it can be increased it can be decreased and it can be generated from nothing, my above two experiments are real world and not some kind of philosophy.

Quote from: Thebox on 19/05/2015 20:43:17 A falling object has no force until it hits something. what ?!! who told you that?!!Quote from: Thebox on 19/05/2015 20:43:17F=ma from Newton, do you understand this?I think you do not understand this equation a falling object undergoes an acceleration which is acceleration of gravity and has mass, so it has force , however I never referred to acceleration, I did not referred to this equation , they are two equal forces in opposite directions, so you misunderstand basic physics and misunderstand me.
A falling object has no force until it hits something.
F=ma from Newton, do you understand this?
Do you understand that a body in space is practically massless? and increases in mass the nearer it gets to a gravitational field?An object that is not influenced by gravity is weightless and massless.

You are doing surprisingly well in this and other posts. Interesting to see you defending science []Hint, don't weaken your argument. An object can have mass, but might not have weight. Weight depends where it is in a gravity field. In some circumstances mass could be thought of as the potential for weight. If you accelerate a mass in 0g it has inertia.Keep up the good thinking!
I started patenting this device to use it in the future.
yes I can. this example will illustrate that I am right an you are wrong :
imagine that there are two surfaces which are perfectly horizontal , they are also identical and they are exactly at the same height ,
one surface is very close to the other however they are distinct they don't touch, now there is a car on the first surface this car has a particular weight W ..
and the first surface exerts a normal force on it equals W ,
there is not any forces on the other surface ,
however suppose the car moved towards the other surface with very little force (no friction) and the car moved totally from the first surface to the second one, now this contradict you said no force can act on a body if there is not something cause the force to begin,
the force acted on the second surface by moving the car with force tend to zero.
also we can increase the normal force on surface 2 by collecting other cars!! moving those other cars with forces tend to zero ,
Quote from: TheboxA falling object has no force until it hits something. It's amazing how many basic things you get wrong. In Newtonian mechanics (not general relativity) a falling object is subject to two forces. One is the force of gravity given by Fg = -mg where m is the objects mass and g is the strength of the gravitational field and the other is the drag force due to the atmosphere Fd. The sum of these two forces is the force on the falling object and is given by the principle of superposition, i.e. F = Fg + FdThis force is most certainly not zero. If the object is falling in a vacuum then all that's left is the gravitational force and that too is not zero.Had you actually chosen to start reading a physics text when we all first suggested it then you'd know this like the back of your hand by now. But since you insist of refusing to follow anybody's advice you remain ignorant of even the most simple physics.
