A conceptual question about motion and rest.

Hehe, when rest and motion are relative to the frame of reference, there is a criterion, and that is speed.

Rather than other subjective feelings, because you think that our four-dimensional space is like a movie, but in fact it ignores the definition of motion and stillness.

To judge the motion and rest of an object, the first is to have a frame of reference, and the second is to measure its velocity, and the individual instantaneous velocities are not isolated from the time before and after, but are related to each other.

So the arrow is wrong.

If the universe is theoretically static, it is static, but that theory cannot exist because nothing in the quantum world is completely static.

But if the macrocosm is concerned, it can be roughly considered to be static.

Calculus is a powerful mathematical method used to describe the world, of course, you can make the above description, because when you describe the universe, you are using subjectivity to describe the objective, whether the subject and object are consistent or not, depends on whether your description is appropriate and whether it conforms to the objective facts.

Therefore, when thinking about anything, it is not necessary to make things that seem complicated more complicated, because all complex things are made up of simple things. As for the Flying Arrow, that is a kind of subjective empiricism, but not in line with objective facts, because that kind of statement treats each 4-dimensional space as completely unrelated "frames", which is only in line with the idea of film scene processing. Stephen Hawking also said that as long as time flows, the world is changing, and people's destiny is changing all the time.

No, motion is absolute, rest is relative!

Relative rest is a special case of motion. It is stationary because the speed of the selected reference is the same as the speed of the object of study (the same size and direction).

You haven't learned the limit. If you understand the concept of limits, you won't make such a mistake. The definition of velocity is:

v=limδs δt(δt- 0) The closer δt is to 0, the closer δs is to 0. When δt is close to 0 (which is never equal to 0), δs δt is close to a fixed value (this value is the instantaneous velocity v at that moment). Limit is a process, that is, a process of change.

It cannot simply be said that δt=0. The above error is simply thinking that δt = 0.

Refutation: Motion is really just the sum of many rests.

The above view severs the connection between time and space, between motion and stillness. It only sees one side of the one side and ignores the existence of the other.

According to the theory of mechanical motion, the motion of an object is to be described. The first thing is to establish a frame of reference before you can determine its state. For the landlord's question alone, I think he is using himself (the observer) as a frame of reference.

That's when he thought the rocket was moving. And when he thinks that the rocket is stationary, it is clear that the frame of reference is the rocket. Both descriptions of the state of rocket motion are not in the same frame of reference.

There is no point in making any further comparisons. Unless the relative motion of the two frames of reference can be determined. Therefore, it is still recommended to hold on to a star as a reference frame to study the motion of the rocket.

Mistake. One is that the earth revolves around the sun, which does not mean that the sun revolves around the earth. Suppose that the mathematical relationship between the sun as a reference frame and the earth as a reference frame is not the same.

The second is that when we see a star every day, it is not that it revolves around us, but that it is formed by our rotation. The third is that your ideas are purely self-imagining and logical reasoning, and cannot stand up to actual verification. Fourth, the relationship between motion and rest on the one hand, and absolute and relative, depends on the specific situation.

It doesn't mean that movement is absolute, or that movement is relative, it depends on the specific situation, otherwise it is the same word.

Motion is the fundamental property of matter, motion refers to the changes and processes that occur in the universe, and it is the fundamental property and mode of existence of matter.

Rest is a special state of motion, which is a state of temporary and stable equilibrium in the movement of matter under certain conditions and within a certain range.

There are two basic situations of relative rest: one is that there is no positional movement between specific things in mechanical motion; The second is that things are in the stage of quantitative change, and there is no change in the fundamental nature.

Stillness, when a particular entity (or entity) has not changed in any way in its spatial position.

Movement refers to the active change of spatial position by an entity in order to maintain its own stability.

Motion is continuous for any entity—so any entity in the universe is always in motion (i.e., not at rest for any period of time that is not zero) until it dies.

Obviously, an absolutely stationary entity does not exist in the universe; What exists in the universe is only relative stillness (refers to the fact that a particular entity has a presence other than the mind of the universe as a reference.

their spatial position or spatial distance from each other, without any change).

It is important to know that the spatial position of any entity in the universe with the center of the universe as a reference object changes with the progress of evolution all the time; The spatial position of the non-celestial center as a reference may not change.

In addition, it must be emphasized that for Dao Neng, movement is active, not passive.

The movement is not due to the unbalanced energy of the sedan chair, which causes a particular entity to passively change its spatial position; Rather, it is a protective change that it takes the initiative to make in order to better maintain its own stability when it is unbalanced.

From this, it can be seen that the autonomy of movement is controlled by specific entities, not by external energies.

Knowing that movement occurs actively, rather than passively, can resolve many questions, such as: Why is the universe expanding? Why is it that the same energy is accepted, and the phenomenon of "the same electricity repels each other, and the sail and the other electricity attracts"?

Movement: refers to the general changes and processes of things.

Stillness: Stillness is relative, which refers to the philosophical category in which the movement of matter is in a state of temporary stability and equilibrium under certain conditions and within a certain range. There are two scenarios for relative rest:

First, there is no movement of the position of a thing in an absolute state of motion relative to a particular frame of reference; Second, when things are in a state of quantitative change, they maintain qualitative stability.

Movement is absolute, unconditional, and eternal. This means that things are in motion no matter what the circumstances.

Stillness is relative, conditional, and temporary. Stillness is an insignificant motion, a special state of motion.

Motion and rest penetrate each other and transform each other under certain conditions, there is stillness in motion, and there is movement in stillness.

It is true that stillness is a form of motion.

Rest is one of the forms of motion, and rest is simply an object that maintains its position with respect to another reference around it. Therefore, to determine whether an object is stationary or moving, it is necessary to choose a suitable reference. If the choice of reference is different, the state of motion will be different.

The relationship between motion and rest.

1) Rest is a special state of motion, which refers to the state of equilibrium, stationary state and quantitative change of matter; Stillness is the concrete form of existence of matter in absolute motion, which is conditionally relatively stationary.

2) Motion and rest are absolute and relative: motion is absolute and unconditional, and rest is relative and conditional.

3) Motion and rest are mutually unified.

1. Mutually contained: there is stillness in movement, and there is movement in stillness.

4) Two kinds of mistakes are made in severing the relationship between the two: exaggerating relative stillness and denying absolute motion is a metaphysical error; Exaggerating absolute motion and denying relative stillness is a mistake in the relativist view of motion.

Motion and stillness are absolute and relative to the relationship between the sensitive.

Movement and stillness are interdependent, interpenetrating, and mutually containing, and there is stillness in movement and movement in stillness. The absoluteness of motion reflects the variability and unconditionality of material motion, and the relativity of rest reflects the stability and conditionality of material motion. Matter is in motion, and there is no matter that is not in motion, which shows that motion is universally eternal, unconditional, and therefore absolute.

However, in the movement of matter, there is a temporary, conditional, and relative stillness. Rest is a special state of motion, a stable state of material motion under certain conditions, including the collision of space, the position of the blind pair and the fundamental nature of things remain unchanged for the time being.

The dialectical unity of motion and stillness.

The absoluteness of motion reflects the variability and unconditionality of material motion, and the relativity of rest reflects the stability and conditionality of material motion. Motion and rest are interdependent, interpenetrating, and mutually containing, relative rest contains absolute motion, and absolute motion also contains a relatively static state, "there is stillness in motion, and there is movement in stillness".

The unconditional absolute motion and the conditional relative rest constitute the contradictory motion of things. Only by grasping the dialectical relationship between movement and laughter and emptiness and stillness can we correctly understand the diversity of the material world and its forms of movement, and can we understand the possibility of recognizing and transforming the world. To deny absolute motion and absolutize relative stillness is to move towards metaphysical invariance; The denial of relative stillness under the pretext of absolute motion leads to relativist sophistry.
