What does inertial force mean 5, what does inertial force mean

It is an imaginary force introduced when using a "non-inertial frame" to investigate the force on an object.

For example, in free fall, if you use an inertial frame to investigate, for example, the earth is used as a frame of reference, and it is subjected to the vertical downward force of MG; But if you use the object itself as a frame of reference, which is a non-inertial frame, then when you analyze its force, you have to have a vertical upward force of f=mg, and this force is called a non-inertial force, which is balanced with gravity, so in this system with the object as a frame of reference, it is stationary.

Note: Inertia is not a force!

Inertia is a natural property of an object and is the property of an object to keep its state of motion unchanged. If you have to explain the inertial force, you can understand it as the effect that the moving object has on other objects in order to maintain their original motion when the state of motion of an object is changed.

The inertial force is an imaginary force introduced in form, without applying force to an object, but is just a concept introduced by people in order to facilitate the problem solving in a non-inertial frame.

Inertia is a property of an object, the magnitude of inertia is determined by the mass of the object, the inertia of a large mass is large, and the inertia of a small mass is small. It can be calculated by this formula: f = is the mass of the object, and a is the acceleration of the object. f is the magnitude of inertia.

Inertial force is a force that does not exist and is just a concept introduced for people to study.

Our junior high school physics teacher said: inertia is not force, and whoever says inertial force in the future will pump him!

It is an imaginary force introduced in a non-inertial frame, and the comrades above are basically correct.

It depends on whether it is in a non-inertial frame or in an inertial frame.

The concept of d'Alembert's inertial force.

Inertial force refers to the tendency of an object to maintain its original motion when it accelerates. The inertial force does not actually exist, only the force that originally accelerates the object, so the inertial force is also called the imaginary force.

Inertial force refers to: when the object has acceleration, the inertia of the object will make the object have a tendency to maintain the original state of motion, and at this time, if the object is taken as a reference frame and a coordinate system is established on the reference frame, it seems as if there is a force acting in the opposite direction on the object to cause the object to be displaced in the coordinate system, so it is called inertial force.

Because the inertial force does not actually exist, only the force that originally accelerates the object, the inertial force is also called the imaginary force. Its concept was developed because Newton's laws of motion do not apply in non-inertial frames. Interaction forces can be observed in both inertial and non-inertial frames, but only in non-inertial frames.
