3.e) Definition of physics acceleration and velocity

The concept of definition of physics acceleration is very simple since it is the change in velocity per unit of time. In the model in Global Dynamics, with Euclidean space and absolute time, the concept is pretty simplified, although new types of movement appear as we have seen in the corresponding section.

There is a problem with the concept of physics acceleration due to the Theory of Relativity and its Equivalence Principle in regards to time and the very same relativity of space.

Logically, the mechanisms that produce physics acceleration in the motion on globine, according to Global Dynamics, are the same that produce the acceleration of movement or velocity, pointed out in its corresponding pages.

On the other hand, someone can think that you cannot eventually distinguish the effects of acceleration of gravity and physics acceleration due to other motives in the reticular structure with radial symmetry, or globine, but in some way we all distinguish it. It could never be said that it is the same to throw a stone at someone's head as to accidentally fall from the fifth floor. That is, in fact, it can be distinguished and, in fact, they are quite different things.

In spite of the previous example, it is true that from a physics point of view, these concepts have many elements in common and it is essential to understand the characteristics of both movements with acceleration in order to establish when they behave the same and in what way a physics acceleration differs from another. And, if possible, escape physics principles that are artificially imposed instead of respecting the empirically observed facts.

Let's take a look at the following example:

• Enchanted forest

  Let's imagine a space with trees where we are going to stroll. It will be an enjoyable stroll if there are not too many trees that impede us from a continuous passage. In other words, there is a specific density of trees that is innate and independent of the observer in this forest. Without a doubt, other forests can be more or less populated.

  Now we are going to a forest to jog, we will notice that we have to be more careful than when we were strolling so as to not run into trees. The faster we go the more crowded the forest seems, that is, physics acceleration changes the subjective density of trees in the forest.

  Now let's imagine but only for a moment that we are giants and we are going for a picnic in the enchanted forest, surely the forest will once again appear more crowded than in the first case.

  Likewise, but in the other way, we could be in three different forests as far as their tree density but that the density perceived by each observer were exactly the same.

  The scientific work in this case is not to maintain this apparent confusion of the forests with relative definitions as a result of the natural subjectivity of our senses.

  Nor it consists in the definition of a different system of measurements’ units for each situation, so that it is impossible to grasp an intuitive idea of reality; by forcing us to constantly change units. And much less force us to calculate equations as if we were in any lost forest of the universe in order to take a small stroll through the woods by the house.

This example of the enchanted forest helps us understand the partial equivalence between gravity and velocity or between variations in the tension of the longitudinal curvature or matter, or globine, the support for gravitational force, and physics acceleration or variation of velocity. As we will later see when discussing movement with gravity, the frequency of resonating mass changes with gravity and with the variations in velocity or physics acceleration due to changes in the movement on globine.

The typical relationship between physics acceleration in globine and acceleration of gravity is elemental physics since the most well-known effect of gravity is a centripetal acceleration by definition, that is, a force by unit of mass that an object endures aimed toward the center of the gravity field of another object.

The physics units of the definition of acceleration of gravity coincide with acceleration. Mathematically, it can be said that the normal concept of gravity is a particular case of abstract acceleration.

Likewise, from the physics point of view, it can be stated that the acceleration of movement on globine exists as a secondary effect or as a result of the existence of gravity, understood as reticular structure with radial symmetry.

Furthermore, as has been repeated on several occasions throughout this book, acceleration due to gravity is a result of the two components of atractis causa that generates global force of gravity. That is, there is no distortion of space or time, just of some physics theories.

Some interesting cases of acceleration due to the force of global gravity are:

• At times, according to the definition of acceleration of gravity, it can be null due to the effect of two gravitational fields balancing each other out; but that the curvature of the filaments of globine does not exist does not mean that longitudinal tension of globine, as a physical or material entity, has disappeared at this point.

• For the orbit of the planets, Newton's Law of Universal Gravitation provides us with the relationships between inertia or centrifugal force and gravity or force of centripetal acceleration that have to exist in order to obtain a stable orbit in the case of planetary orbits. However, the small deviation in the anomalous precession of the planets is only explained by Einstein's General Relativity with its typical mathematical complication and lack of physics sense, and by Global Dynamics with the Merlin effect.

• Another relevant aspect of the development of the theory of gravitation is the force that produces the curvature of light in the presence of a mass. This fact, oddly enough, depends in two times the Newton's force of gravitational acceleration. The cause for which the curvature of light is double is due to the Merlin effect explained in the book, Law of Global Gravity.

The Theory of Global Equivalence is based on the Global Conservation Principle that, as indicated in its name, represents a more general equivalence than that of Albert Einstein's Theory of Relativity, by including gravity together with mass and energy. Nonetheless, it is different and it goes in line with the extension of the classic Principle of Energy Conservation.

On the contrary, as far as the variations in gravity and physics acceleration of motion on globine, the equivalence is more restricted besides being different since it does not end up representing an identity between concepts of acceleration and gravity and much less assign the temporal effects to any of them.

The proposed global equivalence is based on the unification of fundamental forces by Global Mechanics and in the energy effects of physics velocity, acceleration and gravity on mass, studied by the Law of Global Gravity and Global Dynamics.

In the example of the enchanted forest, is equivalent if there are more trees, or that we ourselves move, or even better that the forest moves toward us; to the effects analyzed, the three cases are indistinguishable. But the number of trees is different if we know how to do the calculation.

Lastly, besides not assigning temporal effects to gravity or to physics velocity, Global Dynamics, by explaining the orbit of Mercury and the curvature of light with the Merlin effect makes the physics principle of equality between inertial mass and gravitational mass unnecessary in both Classical Mechanics as Einstein's Theory of Relativity.

The definition of mass in Global Mechanics is based on its physics reality and not for its inertial or gravitational behavior. Physics mass concept is unique in agreement with Global Mechanics and the behavior of mass depends on the forces and energy with which it interacts.

With velocity, mass increases both in the presence of the curvature of longitudinal tension or globine or not, but only with gravity are there also intrinsic variations in the force of gravity by unit of mass as a result of the greater gravitational interaction with greater velocity, explained in the Merlin effect. The variations in force of gravity to which the Merlin effect refers differ from both those derived from the variation in distance and the variation in mass in Newton's formula for gravity.
