Force refers to the action of an object by another object. Otherwise, it is not forced.
There is no such thing as a real absolute inadequacy.
In equilibrium, the object will come to rest or move in a straight line at a uniform speed.
For example, if you sit quietly in front of a computer, you are in a state of equilibrium (you are at rest).
But your identity will obviously feel the effect of force, and you will get tired after sitting for a long time.
So the equilibrium of forces is a state of interaction between objects.
Whereas the absence of force is the nature of the action itself, being or not being there.
-
Force equilibrium means that the net force of the object is 0, not that there is no force. For example, if you pull both ends of a rope with the same amount of force, the rope is balanced, but it is acted on by two forces of equal size and opposite directions other than gravity.
-
The effect of force balance is equal to not being forced, but force balance is not under force.
-
The so-called balance of forces is in terms of its effect. If the deformation and rotation of the stressed object are not considered, and the stressed object is regarded as a particle, then the force balance and the force are the same in terms of effect. Otherwise, the forces must be taken into account.
-
According to gravitational force, any object has to be subjected to force!
The balance of forces belongs to the net force of zero, i.e., all the forces cancel each other out.
-
Of course not.
Your military training is to raise your legs and hold still, then the strength will be balanced, but will you be tired?
-
Force balance and force are not at the same level! The gravitational force exerts force on any object; If the resultant force is zero, the force is balanced!
-
The magnetic force is not the same as the general pressure. The pressure resultant force seen in the usual time is 0, which does not belong to the force. The combined force of the magnetic field is not forced.
-
The force equilibrium is the force applied, and all force potentials are equal to 0
-
Force equilibrium means that the system you are studying has a net force of 0, but it is still subjected to force.
-
The force is balanced and two or more forces are subjected.
-
There are some differences between the force and the balance force, I have sorted out the detailed content, so let's go on and read on.
1.The number of stressed objects is different.
A pair of interacting forces act on two different objects; A pair of balancing forces act on the same object.
2.Dependencies are different.
It is interdependent, cannot exist independently, arises at the same time, changes at the same time, and disappears at the same time;
A pair of balanced forces is independent of dependence, and if one force is removed, the other can continue to exist.
3.Whether the effect can be stacked or not.
The effect of a pair of interaction forces cannot be superimposed, and the resultant force cannot be found; The effect of a pair of equilibrium forces can be cancelled out, and the resultant force can be found and the resultant force is zero.
4.Whether the nature of the force is the same or not.
A pair of interacting forces must be of the same nature; A pair of equilibrium forces can be forces of the same nature or forces of different natures.
Force is the action of an object on an object, so the forces all come in pairs. There is force and force. The force generated by the interaction between two objects through different forms, such as attraction, relative motion, deformation, etc., is called the force.
Since the interaction between two objects is always reciprocal, we call the pair of forces that interact with each other the action force and the reaction force.
Where there is an action, there is a reaction. We can call any of these forces an action force and the other force a reaction force. The neat arrangement of the molecules depends on this powerful force.
Several forces acting on the same object, if the object is still or becomes at rest or in a state of uniform linear motion, or if the net force is zero, then the net force of these forces is zero, we say that these forces are balanced.
Equilibrium forces are also divided into multi-force balance and two-force balance, and the conditions for two-force balance are: the two forces are equal in magnitude, opposite in direction, acting on a straight line, and acting on the same object. Multi-force equilibrium is similar.

Summary. The equilibrium of forces is the state in which the net force of all the forces on an object is zero! The two-force balance is the simplest type of force balance!
That is, the object experiences only two forces, and the resultant of these two forces is zero. When the two forces of an object are balanced, it means that the two forces are equal in magnitude and opposite in direction, acting on the same straight line!
Hello, I am helping you to inquire about the relevant content, and I will reply to you immediately.
Hello, glad for your question, force equilibrium is a state, and the equilibrium of force refers to the state in which the net force of all the forces experienced by an object is zero! The two-force balance is the simplest type of force balance! That is, the object experiences only two forces, and the resultant of these two forces is zero.
When the two forces of an object are balanced, it means that the two forces are equal in magnitude and opposite in direction, acting on the same straight line!

Gravity has nothing to do with the supporting force.
When an object is at rest or in a uniform linear motion, the gravitational and supporting forces on the object are a pair of balancing forces. It is not balanced when it is not in these two states, such as weightlessness and overweight. Of course, this "support force" is a broad concept, which refers not only to the support force of the ground when an object is stationary on the ground, but also to the buoyancy of the air suspended in the air.
Gravity refers to the mutual attraction between an object with mass and rot, and it is also the weight of the object. The calculation formula is: g=mg, g is the scale coefficient, the gravity is about to be the dust leakage, and the gravity will change with the change of latitude.
The force exerted on an object due to the attraction of the earth is called gravity. The direction is always straight downwards and not necessarily towards the center of the earth.
The concept of equipoise
The magnitude of the gravitational force on the object at the same point on the ground is proportional to the mass m of the object, and similarly, when m is constant, the gravitational force of the object is proportional to the acceleration of gravity g, usually near the earth's surface, and the value of g is about, indicating that the gravitational force of an object with a mass of 1kg is.
When several forces are used on the same object, if the object is still at rest or in a state of uniform linear motion, or the net force is zero, then the net force of these forces is zero, and we say that these forces are balanced. When an object in equilibrium deviates from the equilibrium state due to some slight action of the outside world, the equilibrium state of the object can be divided into four situations due to the difference in temperature.
-
Force equilibrium refers to the fact that when an object receives one or more forces, the object maintains its original state of motion.
Two-force equilibrium means that the object is in motion by two forces.
The condition for force equilibrium is that the object remains at rest or in motion at a uniform speed.

Equilibrium force (when two forces) refers to an object subjected to two forces with three characteristics of equal size, opposite direction, and the same line of action, these two forces can be changed in the action time, and the above three characteristics can be changed, but the action time is different or the three characteristics are not available, they are no longer balanced, and they are no longer a balanced force, that is, the situation of each force can be independent of each other, and there is no causal relationship between each other, and they are not interdependent. I can balance with you or I can be unbalanced with you. It is emphasized that one object is acted upon by two other objects, one under force and two by force.
The mutual force refers to the mutual cooperation between two objects, the effect of you on me, I on you, these two forces must be cause and effect of each other, and they arise and disappear at the same time, equal in size, in opposite directions, acting in a straight line, they are so closely related, there must be another if there is one, and if there is no other, then this will not be generated, for example, I push you, you feel my push, but at the same time I also feel your push on me (that is, my hand feels your resistance), And if you retreat and do not stop me, I will not push you, and I will not produce a thrust against you, and here the action of the necessary and mutually causal force between two objects, which are the object of force and the object of force against each other, without regard to the third object. Any force must have a reciprocal force that reacts to it, which is the condition for its production.
-
Equilibrium force: Two forces in opposite directions, acting on the same object, and two forces in the same straight line.
Relative force: Two forces in opposite directions, operating on two objects, two forces in the same straight line.
I hope you can understand this explanation, and if you still don't understand, you can contact me.

The difference between equilibrium force and interaction: There are mainly the following three differences, 1. The equilibrium force acts on the same object, and the action force and the reaction force act on the 1 pair of objects that interact. 2. The nature of the action force and the reaction force are the same, they belong to the same kind of force, and the nature of the balance force force must be the same if it is not exciting.
3. The action force and the reaction force are generated at the same time and disappear at the same time, and the balance force does not have this characteristic.
The similarities between the equilibrium force and the interaction force are: both are equal in size, opposite in direction, and act on the same straight line; The main difference between the equilibrium force and the interaction force is that the equilibrium force acts on the same object, and the interaction force acts on different objects.
That's all for me, I hope it helps.

Summary. Dear dear, it's a pleasure to answer your <>
In the case of force equilibrium, it generally means that the object is at rest, i.e., the object does not produce motion. At this point, the net force of all the external forces experienced by the object is zero, that is, there is no force from the outside world to give the object a downward force. If you look at it from another angle, it can also be said that the gravitational force is equal to the supporting force, so that the object is not affected by the descent.
Thus, in the case of equilibrium of forces, the descending force is due to its own mass and the gravitational pull of the earth, such as gravity acting on an object.
Who gives the force that falls when the force is balanced.
Dear, very ruined, I am honored to answer your <>
In the case of force equilibrium, the fiber generally means that the object is at rest, that is, the object does not produce motion.

If you look at it from another angle, it can also be said that the gravity force is equal to the supporting force, so that the object will not be affected by the descent.
Thus, in the case of equilibrium of forces, the descending force is due to its own mass and the gravitational pull of the earth, such as gravity acting on an object.
How to explain the uniform rise.
Kiss <>
In the case of a constant rise, the object is subjected to two main forces: gravity and buoyancy. Gravity is downward and is the attraction of the earth to the object.
Buoyancy is upward and is the upward thrust of a liquid or gas against an object. When an object moves upwards in a liquid or gas, the buoyancy counteracts the gravitational force, which causes the object to rise at a uniform speed. Thus, it can be said that during the ascent of the object at a uniform velocity, the buoyant force provides an upward thrust to the object.
Is the force balanced when the block rises at a uniform speed in the water?
When the block rises at a constant speed in the water, the force is balanced into a circle, that is, the vector sum of the external forces experienced by the block is zero. According to Newton's second law, the combined force on the block is equal to its mass multiplied by the acceleration, and since the velocity of the block in water rises at a uniform speed, its acceleration is zero, and the resultant force is also zero. However, the block is not at rest, and the buoyancy and gravity it experiences as it rises in the water are balanced, causing the block to rise at a constant speed.
Inertia is present in all objects, there is no object without inertia. For example, when taking a bus and braking suddenly, the upper body of the person standing will lean forward, but the foot will not, because the foot and the car stop together, and the upper body will maintain the nature of the original movement due to inertia, and cannot stop, so it leans forward. >>>More
