Newton s Third Law Equilibrium Force Difference Between Interaction Force?

Balance force, interaction force.

Similarities: The forces are all the same and the direction of action is opposite.

Difference: 1 The interaction force acts on two separate objects, while the equilibrium force acts on one object (essential difference).

2. Under the action of equilibrium force, the object must be at rest or in a uniform linear motion.

states, while interactions are not necessarily.

1.Newton's Third Law:

The action and reaction forces between two objects are always equal in magnitude, opposite in direction, and acting in the same straight line. f

The action of the f-force is mutual. Appears at the same time and disappears at the same time.

The interacting force must be a force of the same nature.

The action and reaction forces act on two objects and the resulting effects cannot cancel each other out.

The action force can also be called the reaction force, but the reference chosen is different.

The action force and the reaction force cannot be found because the application point is not on the same object.

2.The difference between an interaction force and a balanced force.

An interacting force is a force of equal magnitude and opposite directions, acting on two objects and in the same straight line; The nature of the two forces is the same.

A balanced force is two forces acting on the same object, of the same magnitude, in opposite directions, and acting on the same straight line. The nature of the two forces can be different.

Two forces that are balanced with each other can exist separately, but the interacting forces exist at the same time and disappear at the same time.

For example: a rope hangs a bucket, and the vertical upward pull of the rope on the bucket and the vertical downward pull of the bucket on the rope are a pair of interaction forces, and they are both elastic forces. The points of action act on the barrel and the rope respectively.

The vertical upward pull of the barrel on the rope and the gravitational force exerted on it by the earth on the barrel are a pair of balanced forces, and the pull and gravity are not forces of the same nature.

Is the action of force reciprocal Newton's third law? As follows:

The action of force is reciprocal and Newton's third law. Newton's third law of motion: the action and reaction forces between two interacting particles are always equal in magnitude and opposite in direction, acting on the same straight line.

The action force and the reaction force are mutual, interdependent and dependent, and both take the existence of the other as the premise of their own existence, and the force without the reaction force does not exist.

Newton's one-two-three law content.

1.Newton's first eggplant's law states: Any object remains at rest or in a uniform linear motion until it is forced to change this state by the forces of other objects.

2.Newton's second law states: The object will accelerate when it is subjected to the action of the resultant external force, and the direction of acceleration is the same as that of the resultant external force, and the magnitude of the acceleration is proportional to the magnitude of the resultant external force and the inverse proportion of the object's habitual and insignificant elastic mass.

3.Newton's third law states: The force of action and reaction between two objects, on the same straight line, is equal in magnitude and opposite in direction.

Extension: Newton's Third Law:

1).The action force and the reaction force must be forces of the same nature, while the equilibrium force is not necessarily;

2) The action and reaction forces are thought to be on two objects, while a pair of equilibrium forces act on one object to nucleate the middle game;

3) The action and reaction forces are generated, changed and disappeared at the same time.

Newton's Three Laws.

Newton's three laws are important laws in mechanics, and they are the basis for the study of classical mechanics.

1 Newton's First Law.

Contents: Any object remains at rest or in a uniform linear motion until it is forced to change this state by the forces of other objects.

Explanation: Objects have a tendency to maintain rest and move in a uniform linear line, so the motion state of the object is determined by its motion speed, and its motion state will not change without external force. This property of an object is called inertia.

So Newton's first law is also known as the law of inertia. The first law also clarifies the concept of force. It is clarified that force is the interaction between objects, and it is pointed out that it is force that changes the motion state of objects.

Because acceleration describes the change in the state of motion of an object, force is related to acceleration, not to velocity. If you don't pay attention to this in your daily life, you will often have a false impression.

Note: Newton's first law does not hold true in all frames of reference, in fact it only holds in inertial frames of reference. Therefore, Newton's first law is often used as a criterion for whether the frame of reference is an inertial frame of reference.

2 Newton's second law.

Contents: The object will produce acceleration under the action of the resultant external force, and the direction of acceleration is the same as the direction of the resultant external force, and the magnitude of the acceleration is proportional to the magnitude of the resultant external force and the inverse proportion of the inertial mass of the object.

The second law quantitatively describes the effect of the force acting on and quantitatively measures the magnitude of the inertia of an object. It is vector and is an instantaneous relation.

It should be emphasized that the combined external force on the object will produce acceleration, which may change the motion state or velocity of the object, but this change is related to the motion state of the object itself.

In a vacuum, since there is no air resistance, various objects have the same acceleration regardless of their mass because they are only subjected to gravity. Therefore, in free fall, their velocity changes the same in the same time interval.

3 Newton's Third Law.

Contents: The action and reaction forces between two objects, on the same straight line, equal in magnitude and opposite in direction.

Note: To change the motion of an object, other objects must interact with it. The interaction between objects is manifested through force.

He also pointed out that the action of force is mutual, and there must be a reaction force. They act on the same straight line, equal in size and opposite in direction.

Also note:

1) There is no priority or priority between action and reaction forces. Creates and disappears at the same time.

2) This pair of forces acts on different objects and cannot be counteracted.

3) The action force and the reaction force must be forces of the same nature.

4) Nothing to do with the frame of reference.

The action of force is reciprocal and Newton's third law. The third law of motion: the action and reaction forces between the two interacting particles are always equal in magnitude and opposite in direction, acting on the same straight line.

Newton's third motion is the law of accompaniment

Definition: The action and reaction forces between two interacting objects are always equal in magnitude and opposite in direction, acting on the same straight line.

The action force and the reaction force are mutual, interdependent and dependent, and both take the existence of the other as the premise of their own existence, and the force without the reaction force does not exist; Force is material, and cannot be separated from the object (matter) and be cautious; A force is always produced by the interaction between two or more objects.

The action force and the reaction force must be forces of the same nature, i.e., if the action force is elastic, the reaction force must also be elastic, and vice versa. However, there are only four basic types of interactions in nature, namely electromagnetic interactions, gravitational interactions, strong interactions, and weak interactions, so there are only these four properties that distinguish forces in essence, and action and reaction forces must indeed belong to forces of the same nature.

What are Newton's three laws

Newton's three laws generally refer to Newton's laws of motion.

Newton's laws of motion include Newton's first law of motion, Newton's second law of motion, and Newton's third law of motion

The first law explains the meaning of force: force is what changes the state of motion of an object;

The second law states the effect of force: force causes an object to gain acceleration;

The third law reveals the nature of force: force is an interaction between objects.

Newton's third law of motion states that when two objects interact with each other, the forces exerted on each other, equal in magnitude and in opposite directions, act on the same straight line.

The action force and the reaction force are mutual, interdependent and dependent, and both take the existence of the other as the premise of their own existence. The force without a reaction force does not exist in the town of Imperforation; Force is material and cannot exist apart from the object (matter); A force is always produced by the interaction between two or more objects.

Newton's third law also has an instantaneous nature, that is, the coarse temporality of the coarse time of the action force and the anti-Wang Xiao force, which are generated, disappeared and changed at the same time.

What is Newton's law that states that "force is an interaction between objects"?

1.One. 2.Three.

Correct Answer: Three.

A common formulation of Newton's third law of motion is that the action and reaction forces between two interacting bodies are always equal in magnitude and opposite in direction, acting on the same straight line. This law was proposed by Isaac Newton in 1687 in his book Principles of Mathematics in Natural Philosophy.

Newton's third law of motion and the first.

The first and second laws together form Newton's law of sail motion, which expounds the basic laws of motion in the classical mechanics of the hail.

Newton's first law of motion, abbreviated as Newton's first law. Also known as the law of inertia, the law of inertia. A common full formulation: any object must remain in a uniform linear motion or at rest until an external force forces it to change its state of motion.

1. Newton's first law of motion: When all objects are not affected by external forces, they always maintain a uniform linear motion or a state of rest, which is the law of inertia. Illustrates that all objects have inertia.

2. Newton's second law of motion: the acceleration of an object is directly proportional to the resultant external force on the object, inversely proportional to the mass of the object, and the direction of acceleration is the same as the direction of the resultant external force.

3. Newton's third law of motion: the force and reaction force between two objects, in the same straight line, are equal in magnitude and opposite in direction.

Newtonian mechanics belongs to the category of classical mechanics, which takes the particle as the research object, focuses on the action relationship of force, and emphasizes the consideration of the force on each particle point when dealing with the problem of the particle system, and then deduces the motion state of the entire particle system. Newtonian mechanics holds that mass and energy exist independently and are conserved separately; Inertial frame of reference that applies only to the motion of an object; Newtonian mechanics mostly uses intuitive geometric methods, which is more convenient and simple than analytical mechanics when solving simple mechanical problems.

In mechanics, Newton clarified the principle of conservation of momentum and angular momentum and proposed Newton's laws of motion. Optically, he invented the reflecting telescope and developed a theory of color based on the observation that a prism diverges white light into the visible spectrum. He also systematically formulated the law of cooling and studied the speed of sound.

In mathematics, Newton shared the honor of developing calculus with Gottfried Wilhelm Leibniz. He also proved the generalized binomial theorem, proposed the "Newtonian method" to approximate the zero point of a function, and contributed to the study of power series.

In economics, Newton proposed the gold standard.

Cattle law (law of inertia): all objects always remain at rest or in a state of uniform linear motion without being acted upon by external forces.

Ox law: The acceleration of an object is directly proportional to the resultant external force and inversely proportional to its own mass (f=ma).

The three laws of the ox: the action force and the reaction force act on two objects respectively, they are equal in size, opposite in direction, act on the same straight line, and disappear at the same time, the nature of the force must be the same.

For example, a small ball at rest on the ground, which is subject to gravity and support, is a two-force balance rather than action and reaction.

Difference 1: The balance of two forces acts on one object, and the action and reaction forces act on the two objects.

Difference 2: The two forces balance the two forces with different properties, and the action force and the reaction force are the same.

Difference 3: Two forces balance the generation of two forces and two forces. Disappearance does not affect each other, and the action force and the reaction force are generated at the same time and disappear at the same time.

Difference 4: The balance of the two forces can be canceled out, and the action force and the reaction force each have their own effects.

Of course there are differences.

They differ in the following ways:

1. The subjects of the study are different:

The object of the three laws of the bull is different objects, i.e., the force of A on B and the force of B on A are mutual forces and reaction forces The balance of forces refers to the force on the same object, that is, A or B alone

2 The nature of the force is different.

The action force and the reaction force are forces of the same nature, such as the elastic force of the book on the desktop on it and the elastic force of the book on the desktop are mutual action and reaction forces.

The nature of the balancing force is not necessarily the same, such as the gravity and tension of a fan suspended under the ceiling

3. The generation time is different.

The action and reaction forces arise at the same time and disappear at the same time and for the equilibrium force, as shown above; There is gravity first, and then there is elasticity

4 The effect is different.

The action and reaction forces acting on different objects cannot be cancelled out, while the equilibrium forces acting on the same object can be cancelled out
