How is force generated, what is the role of force What is the role of force

I think force is just a phenomenon that we feel, and in the final analysis, it is the law of conservation of energy at work, that an object can transfer energy to another object or be lost to the outside space through contact or magnetic field, etc., so that we see the table being pushed and so on, that is, our conceptual force. Do you agree!

Force is an interaction between objects and is an objective phenomenon. 1。Collective:

It must be between two or more objects for it to occur. 2。Reciprocity:

A gives B a force, and B also gives A a reaction force. The two are equal in size and opposite in direction. 3。

Simultaneity: The action and reaction forces are generated and eliminated at the same time.

The definition of force is the rate of change of the momentum of the object, we find that the momentum of the object changes when the object acts with the object, in order to express this action we define the force, and use its magnitude to represent the magnitude of the rate of change, so force is a definition concept, it is closely related to the change of momentum of the object, and we say that the change of the momentum of the object is produced by the action between the objects, so we go back to the original discussion, not so much that the interaction between objects produces force, but that the interaction between objects defines the force, Or we can understand this interaction as a force, and now the question becomes "what is the interaction between objects, and how does it arise", people initially discovered that there is a interaction between objects, and did not discuss its nature, until Einstein, he proposed that gravity is generated by the curvature of space-time (general relativity), which is a very great discovery, which allows us to understand the universe more clearly, and rise to the realm of time and space to understand the universe. Time and space are more intuitive than forces (or interactions), the force affects the object, the object and the influence rises to the curvature of space-time affects the object, and the object affects the curvature of space-time, the curvature of space-time compared with the abstract force (interaction) can be imagined to be a big progress, but this is only gravitational force, I don't know much about the strong and weak interaction and electromagnetic interaction in quantum mechanics, I hope some of my views can give you some help, if there is something incorrect, please point out and discuss.

Because an object wants the state or shape of another object to change under certain conditions, the object moves towards the other object, and the moment the two objects come into contact, they act. At first, people did not know what this effect was called, and what to use to describe it, and later, people gave this effect a name - force.

On the macro level, it is the interaction between objects, and on the micro level, it is the force between the molecules of two objects, and if you squeeze them hard, the molecules between the two objects will be too close to each other and repel each other, which is pretty much the same thing.

Force is generated after the conversion of energy Force material motion The above is the process that I conceived the landlord's question, what the landlord wants to understand is how the force is generated, that is, what it is, first of all, it can be seen from the process that the force is not an initial state, and it has to go through several procedures before it. The first thing I want to explain is that force is actually the result of a transformation of a certain factor, which is actually energy. Including the four elements, wind, fire, water, and electricity, all of which can be converted into energy, it is even more difficult to explain, because only by knowing how things are formed can we know what they are.

The above is my personal opinion.

The interacting objects will be deformed, and if the object wants to return to its original state, there is a force generated.

You can feel it by trying to push something else.

1. Force refers to the interaction between objects. Interaction is when the motion of one object changes due to the presence of other objects. Force is the action of an object on an object, and force cannot exist independently of the object. The action of force can also arise between two objects that are not in direct contact.

2. Knowing that force is the effect of an object on another object, knowing that force cannot exist apart from the object, and being able to determine the object of force and the object of force. Know that the action of forces between objects is reciprocal. Knowing that force can change the state of motion of an object and can also change the shape of an object.

3. The concept of force is very abstract, and the effect of force is to understand the concept of force.

Force is the action of an object on an object, the force cannot exist separately from the object, the action of force may also arise between two objects that are not in contact, and the action of force is mutual.

Generally speaking, there can be three types of forces acting on any larger object:

There is an external force on the area of some points or certain surfaces that are dispersed.

Inside the object, there is the action of a reaction force generated by an external force, or an internal binding force due to the deformation of the object. These internal deformation constraints are generated in pairs, and together they cancel each other out and do not affect the acceleration.

It has the effect of distributing forces in various parts of the interior. These forces are generally proportional to the mass of the parts. For example, the force exerted by weight and the inertial force caused by acceleration are both forces distributed within the body.

Diagram of force:

The diagram of a force contains three elements: the magnitude, direction, and application point of the force. The way in which the three elements of a force are accurately expressed in a directed line segment is called a force diagram. The magnitude is represented by the length of the scaled line segment, the direction is indicated by an arrow, the point of application is represented by an arrow or the tail of an arrow, and the straight line along the direction of the force is called the line of action of the force.

When judging the magnitude of the force, you must pay attention to the scale of the line segment, because even if one line segment is longer than the other, but the scale of the long line segment is also long, the force represented by the ** segment is not necessarily smaller than the force represented by the long line segment.

With quantum mechanics: it is because there is a mutual exchange of particles between objects. So there is a force effect. In simple terms: force is the interaction between objects. As long as there is interaction between two objects, there is a force.

What is the role of force

Force is produced by the action of an object on an object, or the interaction between matter and matter.

The magnitude, direction, and application point of force are the three elements of force.

A force cannot exist separately from an object, and the action of a force can also occur between two objects that are not in direct contact.

The effect of force is that it can change the shape of an object and also change the state of motion of an object.

According to the nature of force, it can be divided into: gravity, gravitational force, elastic force, frictional force, molecular force, electromagnetic force, nuclear force, etc.

According to the effect of force, it can be divided into: tension, tension, pressure, support force, power, resistance, centripetal force, recovery force, etc.

Force is what changes the state of motion of an object. Force is the action of an object on an object, and force cannot exist independently of the object. The action of force can also arise between two objects that are not in direct contact.

Newton's second law reveals the causality of force and motion: force is the cause of acceleration, acceleration is the effect of force, and therefore force is the cause of changing the state of motion of an object.

The common formulation of Newton's second law of motion is that the acceleration of an object is proportional to the force, inversely proportional to the mass of the object, and proportional to the reciprocal of the mass of the object; The direction of acceleration is the same as that of the applied force. This law was proposed by Isaac Newton in 1687 in his book Principles of Mathematics in Natural Philosophy.

Newton's second law of motion and the first.

The first and third laws together constitute Newton's laws of motion, which expound the basic laws of motion in classical mechanics.

Force is the action of an object on an object.

Force is one of the fundamental concepts in mechanics and is the external cause that causes an object to gain acceleration or deformation. A force cannot exist separately from an object, and the action of a force can also occur between two objects that are not in contact because the action of force is reciprocal.

The concept of force. The SI unit of force is Newton, abbreviated as the ox, and the symbol is n, which is named in honor of the British scientist Isaac Newton. The movement of the object being pushed and pulled, and the gradual slowing down of the object due to friction and finally stopping when the object slides are all reflections of the force.

The ancient Chinese document "The Book of Ink" summarizes the concept of Huaiye Xun as "force, the form of the cause of the struggle." That is, the force is what makes the object move. So, the force is naturally reflected in the consciousness of the person.

The discovery of force. Newton came up with the definition of force. Newton's first law is a qualitative definition of force, which gives qualitative conditions under what conditions a force exists and under what conditions it does not.

Newton's second law gives a quantitative definition of force, i.e., the temporal variability of force equal to momentum; If the mass is constant, the force is also equal to the mass multiplied by the acceleration. Newton's third law states that for every force, there must be a reaction force of equal magnitude and opposite directions.

The force is what changes the state of motion of the object, that is, what produces the acceleration.

The motion of an object does not require force to sustain it, and the motion of an object is determined by its own properties (inertia).

If it is not forced, it will remain stationary when it is stationary, and it will maintain a uniform linear motion state when it is moving.

The nature of the force. Materiality: Force is the action of an object (matter, mass) on an object (matter, mass), an object is affected by a force, there must be another object exerting this effect on it, and the force cannot exist independently of the object.

Reciprocity (reciprocal force): The action between any two objects is always reciprocal, and the object applying force must also be the object receiving the force. As long as one object exerts a force on another object, the stressed object in turn will certainly add a force to the object to which the force is applied.

Generating conditions: The forces are equal in magnitude (the resultant force is zero and in a directionless state of stationary motion) or unequal, in opposite directions, acting on two different objects and acting on the same straight line. In a nutshell:

Foreign Body, Equivalence, Inverse, Collinear. A pair of interacting forces must arise and disappear at the same time.

Vectorality: A force is a vector quantity that has both magnitude and direction.

Simultaneity: The force is generated at the same time and disappears at the same time.

Independence: The action of one force does not affect the action of another force.
