Why inertia has nothing to do with velocity 30

Inertia, is a property of an object that is only related to the mass of the object. inertia, which does not get bigger or smaller. Velocity only affects the kinetic energy possessed by a moving object.

Here's an example: a car is moving at a normal speed, and the passengers only rush forward after braking.

When the car was driving at super high speed again, a sudden braking passenger flew out (exaggerated).

A car is driving at a normal speed, and the passengers only rush forward after braking: because after braking, the car stops moving, and the passenger's upper body rushes forward because the inertia still maintains the original speed to do a uniform linear motion.

When the car was driving at super high speed again, a sudden brake passenger flew out (exaggerated): it was the same reason, because after braking, the car stopped moving, and the passenger's upper body flew out because the inertia still maintained the original speed to move in a straight line.

Inertia: the original stationary nature to remain stationary, the original high-speed driving to maintain the nature of high-speed driving, the original speed is 3 meters per second to keep 3 meters per second unchanged.

There is such a passage in the textbook: an object with a small mass is easy to change its state of motion, and we say that its inertia is small. For an object with a large mass, it is difficult to change the state of motion, and we say that it has a large inertia.

If we are in a vacuum and cause two objects A and B to collide at much less than the speed of light, we get Fa=Fb, then Fa=(ma)(A1),Fb=(MB)(A2) according to the equality of the action and reaction forces

Here we can judge the ease of changing the state of motion by the magnitude of the acceleration, and we can get the above sentence.

In real life, we often mistakenly believe that the faster the speed, the greater the inertia. Actually, this is wrong.

Why is it related?

The property of an object that remains in a constant state of motion is called inertia, regardless of whether it is moving or at rest.

The magnitude of inertia is not related to velocity. The magnitude of inertia is not related to the state of motion. The magnitude of inertia is only related to the mass of the object.

The property of an object to remain at rest or in a state of uniform linear motion is known as inertia. Inertia is an intrinsic property of an object, which is manifested as a degree of resistance of an object to a change in its state of motion, and mass is a measure of the magnitude of an object's inertia.

When the external force acting on the object is zero, the inertia is manifested as the object keeping its state of motion unchanged, that is, keeping it at rest or moving in a straight line at a uniform speed; When the external force acting on the object is not zero, inertia is expressed as the degree of difficulty with which the external force changes the state of motion of the object. Under the action of the same external force, the object with less acceleration has a larger mass and greater inertia, and the object with a larger acceleration has a smaller mass and less inertia.

Therefore, the inertia of an object will not change at any time (with or without external force) and under any circumstances (rest or motion), let alone disappear.

The greater the mass, the greater the inertia.

The definition of mass is divided into gravitational mass and inertial mass.

Inertial mass – The mass of an object is equal to the amount of force required to cause the object to produce a unit of acceleration.

m=f aThe greater the external force required to produce the same acceleration of the object, the greater the inertia of the object and the greater the mass, and the magnitude of the inertia indicates how easy it is to change the state of motion of the object.

The magnitude of inertia is not related to velocity, only to the magnitude of mass.

Inertia refers to the property of an object to keep its original state of motion unchanged, and the velocity is a state of motion and is related to kinetic energy, so it can only be said that the greater the velocity, the greater the kinetic energy, not inertia, inertia is just a property.

The magnitude of inertia is only related to mass, not to velocity.

The property of an object that remains at rest or in a constant linear motion is called inertia. Inertia is the inherent nature of all objects, and inertia exists objectively and has nothing to do with the motion state of the object, whether it is subjected to force or not.

Definition of inertia: We call the property of an object in its constant state of motion inertia. Inertia represents how easy it is for an object to change its state of motion.

The magnitude of inertia is only related to the mass of the object. It is relatively difficult to change the motion state of an object with a large mass, that is, it has a large inertia; The motion state of an object with a small mass is relatively easy to change, that is, the inertia is small.
