Can the so-called internal force be explained by physics?

In fact, physics, or more accurately, mechanics, has the concept of internal force.

Internal force in mechanics

In mechanics, internal force refers to a kind of force generated inside an object under the action of external load. We hulk hand split bench stretch as an example, as shown below. The bench as a whole by gravity, support force, and huluwa foot force, its hand has not split to, so there is no split force.

The analysis of internal force, using the cross-section method. The object of study is "divided into two", any half as the object of analysis. In addition to the original external load, the object to maintain equilibrium, in this imaginary cross-section must be balanced with the external force, this force is the internal force. Since this cross section is imaginary, this force is internal to the object.

The nature of internal forces in mechanics

Macroscopically, internal forces are resisted external loads. Such as tension, compression, and shear, all generate corresponding internal forces within. When it comes to the microscopic perspective, objects such as common metals are crystalline materials and have a crystalline structure, as shown below.

Inside the object, atoms are arranged with atoms like the picture above. There exists a force between atoms and atoms which is electromagnetic in nature. Under the action of this force, they cannot be too close to each other or too far away from each other. The distance between the atoms inside the object changes under the action of external loads, and the macroscopic manifestation is the internal force. Therefore, the nature of internal force is electromagnetic force.

Some of the concepts of "internal force" summarized by the ancients are in line with the rationale of fighting.

But other than that, the movie's what the mountain to beat the bull, the space to hurt, what healing, this is all martial arts novels play, is not based on anything at all. Online Yan Fang masters have dried martial arts into a large comedy show, can only say that the people who believe in it really have a pit in the brain.

And the so-called internal force, and modern science under the guidance of the training is simply two different things, even if you meditate every day to practice internal force, as long as your muscle power and their own reaction speed can not keep up, then still be hung up on the part of the people. As if facing the following speed and strength, not to mention the internal force, the Golden Bell Shield Iron Cloth Shirt Dragon's Eighteen Palms together are useless.

Warrior internal force explanation

Warrior internal force, is able to produce effects on the human body. Then how to explain it? Scientific point of view, of course, can not be explained. Because this internal force, not scientific at all. However, we can force the explanation. The following part is bullshit, read with caution.

In the world of martial arts, practicing martial arts is essentially more than just a stance, it's a kind of energy that accumulates in the body. This energy presents itself in a particle state, which can be electrons, plasma, and so on. The six chakras of the divine sword, shooting out is actually plasma. Through the gong method, absorbing particles in nature and letting it run in the body, driving the particles in the body, thus accumulating more and more, and the internal energy becomes deeper and deeper. Therefore, from this perspective, martial arts internal force is also a kind of electromagnetic force.
