What is the difference between two force balance and inertia, and the difference between two force b

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.

The balance of the two forces is to receive two forces, and these two forces are equal to the greatest, reversed, and cancel each other, which is equivalent to no force. This equilibrium can be static or dynamic.

Inertia is the uniform linear motion of an object without being acted upon by an external force.

Second, the balance of force is that the object is at rest and can be stationary or move in a straight line at a uniform speed.

The two forces are balanced, and the stressed object has been subjected to force.

Inertia, the stressed object has not been subjected to force.

It's a joy to help others! Flash!

It's not a good question, classmate, you don't look like a good student.

Equilibrium Force: Several forces acting on the same point, the vector sum of which is 0, is a set of equilibrium forces. To put it simply, for two forces, if they are equal in magnitude and opposite directions, acting on the same object, then the two forces are a pair of balanced forces.

Two forces are balanced. An object is acted upon by two forces and remains at rest or in a state of uniform linear motion, and these two forces are a pair of balanced forces, which is called two-force equilibrium. That is to say:

If an object remains at rest or in a straight line at a uniform speed, the force on it must be a balanced force (or no force)".

Two forces balance andInteraction forcesThe differences:1EquipoiseActing on the same object, the stressed object is the same; Interaction forces act on different objects, and the exerting object and the stressed object are just the opposite.

2.Equilibrium forces can be forces of different natures; The base parsley pin interaction force must be a force of the same nature, and it is generated and disappeared at the same time.

The reciprocal force, one of the fundamental forces of the universe, is a condition for the establishment of the game: as long as one object exerts a force on another object, the object receiving the force will in turn certainly exert a force on the object applying the force.

In the movie "Captain America 2", the director of S.H.I.E.L.D. is hunted and killed by the Hydra organization. Nick drives a car that resembles a tank and goes all the way. Bucky dropped a bomb under the chassis of the car, and the bomb**, the car's uniform speed and straight driving state were instantly subverted.

So how can you keep an object moving in a straight line at a uniform speed?

The magnitude is the same, the direction is opposite, and in the same straight line, there is no interacting force, such as an upward pull force and a downward gravity force.

When the object is not subjected to force or is subject to equilibrium force, it should remain at rest or in a state of uniform linear motion, that is, when the object at rest is not subject to force or equilibrium force, it still remains (

stationary); When a moving object is not subjected to a force or is subject to a balanced force, it remains in a uniform linear motion.

State.

Two forces are balanced. If an object can remain at rest or move in a straight line at a uniform speed when it is subjected to two forces, we say that the object is in equilibrium. The two forces that keep an object in equilibrium are called equilibrium forces.

Two forces acting on an object, if the object remains at rest or in a uniform linear motion, then the effects of these two forces cancel each other out (the net force is 0), we say that the two forces are balanced.

Conditions for the balance of forces.

Size: Equal.

Direction: Opposite.

Other conditions: acting on the same straight line, acting on the same object.

Effect: The object remains stationary or moves in a straight line at a uniform speed.

Two forces acting on the same object, if they are equal in magnitude, opposite in direction, and on the same straight line, the two forces balance each other.

An object can be subjected to multiple forces, vertical upward support force and vertical downward gravity force, etc. At this point, the object is stationary or moving in a straight line at a uniform speed.

Inertia is an intrinsic property of the sail chain that the object itself has. The magnitude of inertia can be measured in terms of the mass of the object, and the greater the mass, the greater the inertia.

The equilibrium force refers to the fact that the net force of several external forces experienced by an object is zero. For example, when an object placed on the horizontal ground is stationary, the jujube is subject to the gravity and support force of the judgment car, and the magnitude of these two forces is equal and the direction is opposite, and the resultant force is zero.
