Newton's third law of motion, also known as the law of action and reaction: the action and reaction forces between two interacting objects are always equal in magnitude and opposite directions, acting in the same straight line.

The effect of recording is that the action and reaction forces can be operated to a limited extent, and the effect can fluctuate by about 10%.

In other words, when you attack someone, the impact they receive can be strengthened by 10%, and the shock you receive can be reduced by 10%; When someone attacks you, the shock can be reduced by 10%, and the enemy's shock can be strengthened by 10%.

Or, when others are suppressing you and you are suppressing others, you can adjust the direction of the force appropriately so that it is not on the same line.

The law of gravitation: any two particles have a force in the direction of a central line that attracts each other. The magnitude of this gravitational force is directly proportional to the product of their masses and inversely proportional to the square of their distance, independent of the chemical composition of the two objects and the type of medium in between.

The effect of recording is that it can perform limited gravity manipulation on itself or the objects it touches, and the effect is about 20% up and down.

This means that nearly half of the weight loss effect of free running can now be blessed on the body at any time, although Cheng dù is much smaller, but this trick not only reduces, but also ≮≌ weight gain, not only to yourself, but also to others, and the duration is also greatly extended, and the applicability is definitely greatly improved.

The classical law of friction, also known as the Amunton-Coulomb law: 1. The friction force is proportional to the normal load; 2. The friction factor has nothing to do with the contact area; 3. The friction factor has nothing to do with the sliding speed; 4. The static friction factor is greater than the dynamic friction factor.

This is the law that expresses and defines friction, and the corresponding recording effect is, of course, the frictional operation of an object. Let the friction force be based on the real number jù. Up and down 20%.

Don't underestimate this trick, the bullet is out of the chamber. The speed will become slower and slower, precisely because of the frictional resistance of the air. Blessed with this trick. The velocity of the bullet will be weakened slower, the range will be longer, and the trajectory will be straighter.

Not only that, but this trick can be combined with Newton's first law of inertia.

One can reduce friction, the other can maintain greater inertia on the object, and the 20% effect of each 2 can be combined to increase the range of the bullet by half.

Moreover, in addition to being used here, it can also be used by jumping from a high altitude. However, the opposite operation - increasing the air friction and reducing the falling inertia can directly reduce the ultimate speed of the free fall by a lot. If you add gravity to 20% of the body weight reduction...... Originally, Xiao Ling, who was only sure to jump from two or three floors without being injured, could raise the limit height to four or five floors.

Oh, by the way, and then use the law of action and reaction to reduce the impact exerted by the ground when you fall to the ground, and the limit can be one level higher.

It's a pity...... At the moment, he only has two title pages of truth, and can only trigger two effects at the same time.

So. How to arrange the trade-offs of these laws of truth, and how to apply them in the face of various situations after they are written on the title page, has become the focus of Xiao Ling's special training in the next period of time!

Wait a minute. I'm not done yet. In addition to Newton's three laws, gravitational attraction and classical friction laws, there is one more law. It is the last item that Xiao Ling can write into the title page of truth and realize at present, and it is also the last one-Hooke's law. Or Zheng Xuan's law of elasticity.

It is expressed as follows: after the force of a solid material, there is a linear relationship between the stress and strain (unit deformation) in the material.

This is a crucial law!

The law itself allows Xiao Ling to apply to the stubbornness coefficient of solid elastic materials. In addition to adjusting the elastic coefficient, it also gave him a crucial ability to replicate elastic materials.

Elastic deformable materials, because they are not rigid bodies, undergo various deformations, which cannot be replicated by intelligence alone, and require the cooperation of sensibility.

And now that Hooke's law is written on the title page, Xiao Ling can ignore the limits of sensibility.

Springs, bowstrings, rubber ...... All solid elastomers can be easily replicated. If he needed to manifest blood drops again, he didn't need Pu Rou's help, he could do it alone.

"I'll go! You're ...... The contract field can still be used like this, and with the characteristics of the rules, it's fucking amazing! Dong Gossip helped Xiao Ling sort out these laws one by one, and then watched with his own eyes that after the laws were written on the title page, the ability he had acquired, he shouted, was speechless, and couldn't help but burst into foul language.

These abilities, the effect looks okay, but ...... It's just okay, as a scholar like Dong Bagua, as for being so yelling?

As for it, it's so much! Necessary, so necessary!

Don't look at the theorems and laws selected by Xiao Ling, they are all learned in junior high and high school, and they are already rotten on the street, but they are by no means so simple.

Why is it that these seemingly ordinary laws, even if you know them, can't use them at all, and you have to reach the doctoral level or even higher to use them?

This is because ...... All of these statements are not entirely correct, but they are only correct within a certain scope and within a certain limit.

It's like Newton's one-two law, which is true in normal cases, but if the object is moving very fast, very fast, approaching the speed of light, and thus causing a change in mass, it is not accurate.

The law of gravitation is also limited to the large framework of low velocity, macroscopic and weak gravitational force, and is not applicable to high-speed, microscopic and strong gravitational force. The over-distance effect of gravity cannot be explained, and the precession of Mercury's perihelion does not correspond to observations......

Take Hooke's law as an example, Hooke's law actually only applies to linear elastic materials, and ...... It is only suitable for cases where the deformation of the linear elastic material has not reached the elastic limit.

Oh, that is, in "Prison Break", the male protagonist drills holes in the wall to reduce the elastic limit of the wall.

In fact, the vast majority of deformations in nature are inelastic deformations, for example, rubber bands are broken, springs are aging and deformed;

Collisions are also mostly not elastic collisions under ideal conditions, but completely inelastic collisions, such as water droplets falling to the ground, bullets burrowing into wood, and two dough collisions together...... This again makes conservation of kinetic energy problematic.

After talking about Hooke's law, let's talk about the law of friction.

The classical laws of friction are only for solids, but in fact, the friction between liquids and gases is more applicable.

Newton's law of internal friction pioneered fluid physics, followed by Darcy's law which expresses the concept of osmosis, Fuchy Heim's law for nonlinear osmosis, Bernoulli's law and Poissoule's law applied to fluid science, and Plante-Grauert's law applied to aerodynamics, the Plante-Meyer flow model, and the high-speed boundary layer theory......

This is just physics, like a big tree, branching out from the branches of traditional physics, giving rise to one field after another, each of which broadens the understanding of the world on the basis of the previous field.

Without an understanding of the top level of the field, without a full understanding of the limitations of the current rules, it is impossible to use the corresponding abnormal abilities.

Therefore, even in the most basic field such as classical mechanics, if you want to have the ability to match, you need at least doctorate-level knowledge;

If on this basis, the ability to go further, the doctor is not enough, at least to be able to bring the doctor's program, or even ...... Open up your own field of Cheng dù!

There are so many people engaged in science in the world, how many can create their own fields?

The more advanced science goes, the more difficult it is to understand and explore. If nothing else, one aerodynamics is enough for a lifetime of research, but is physics just one aerodynamics?

Of course not!

Classical mechanics includes statics to discuss the engineering structure and load analysis of bridges and culverts; There is kinematic analysis of motor characteristics; There are dynamics that study the relationship between force and motion...... There are also vector mechanics and analytical mechanics; acoustics of the edges; Thermodynamics; statistical mechanics; Covers electromagnetism, magnetostatics, electrodynamics and optics......

Modern physics covers more and more fields: relativity, quantum mechanics, particle physics, nuclear physics, atomic and molecular physics, solid state physics, condensed matter physics, laser physics, plasma physics, geophysics, biophysics, astrophysics......

This is listed, and there are many more that are not listed, and each of them is worth a lifetime of studying!

It can even be said that if you don't have the ability to pioneer scientific research, even if you master the ability, it will not be too high-end.

The more high-end the ability, the more powerful it is, but the more difficult it is to master.

And what about Xiao Ling...... Completely breaking the limitations of the supernatural realm, through his own learning, as well as the joint efforts of his own traits, Heavenly Mandate Armament and contract fields, he directly lowered his doctoral-level ability to the undergraduate!

Although Cheng Dù's ability is much weaker than that of the doctor, at least he is capable, isn't he?

The most important thing is! There are enough types of skills!

Other people can only master one or two fields with all their best in this life, after all, doctoral-level academic ability is not so easy to achieve, and the modern discipline distribution, even geniuses cannot be omniscient.

But Xiao Ling ...... He continued to study and perfected the law of friction, and it was estimated that he could embody fluids;

After learning the three laws of thermodynamics, the ability to conserve energy and conduct heat should also be able to be put on the table;

After learning Faraday's laws of electromagnetic induction and Maxwell's equations, you will become Magneto.

It's true that he is not very strong in everything, but he can really have a lot of tricks! All-rounder, which is completely impossible for others to achieve, may really be able to achieve if he works hard.

The only thing that limits him is the number of title pages of truth. (To be continued......)
