What would the world look like if inertia decreased or disappeared?

Convert the energy in advance, the inertia will be reduced, or even not generated, inertia is the buffer of the movement of things, if there is no one, then it is a hard hit, miserable, to be clear, if there is no inertia in the world, then the world will not exist.

The inertia will disappear, then the gravitational force will disappear accordingly, and you can fly freely in the air and experience the feeling of flying, but you can't just stop, you can not know where you will fly and how long you will fly.

If there is really no inertia, then if you jump vertically on the ground, you will reach a distance of several thousand meters, and everything in the world will appear flying in the sky, and all the world will not exist.

If the inertia disappears, then flying is no longer the patent of the airplane, with the eyes closed is floating around, it is estimated that it will float to the moon, Mars is still a little far away, our clothes can need to be redesigned, after all, the gas is mixed together, it is estimated that everything will be mixed together at that time.

Inertia is the most fundamental property of any substance. Without inertia, there is no matter, and the world does not exist. Everything remains in its original state, not to mention the lives of us humans.

The sea water will float freely in the air, and in this salty air, you can only breathe for 5 seconds; Broken mountains also float above you, and the dirt will crumble into small pieces of dust; All the artificial products are also floating in front of your eyes. When you want to grab your favorite chocolate cake, it just sticks you in the face with chocolate cream and floats upwards.

Everything that has mass must have inertia (the concept of inertial mass), or in other words, without inertia, there would be no object with mass in this world. The rest is not hard to imagine.

Inertia refers to the property that all objects have the property of maintaining their state of rest or in a state of uniform linear motion. If there is no inertia, the stationary state cannot be maintained, and the monitor on your desk does not know when it will run under the table; The sofas, tables and chairs in the room, the beds, cabinets and all the unfixed objects in the room will move with the cherry blossoms and collide with each other, and the room will be chaotic; Commodities cannot be arranged, cars cannot be assembled, people cannot be piled together, objects that cannot be fixed with the earth will move at any time, collide with each other, and will be desperate without a moment of peace.

After losing inertia, the world becomes terrible.

Then the earth will fall apart, nothing will exist, and the earth will not exist.

1. According to Newton's classical mechanics theory, inertia is an intrinsic property of an object, which is only related to its mass, and has nothing to do with its motion state and velocity. The greater the mass, the greater the inertia.

2. According to the theory of relativity, the greater the velocity, the greater the mass of the object, and the greater the inertia; Conversely, the lower the velocity, the less mass and less inertia.

3. Newton's classical mechanics theory is applicable to macroscopic and low-speed situations. In fact, in this case, the change in velocity will still cause a change in mass, and once the mass changes, it will cause a change in inertia, but the amount of change is very small, and it can be ignored in conventional calculations.

The theory of relativity applies to macroscopic, high-speed situations, and when the speed is greater than 1 2 The speed of light, the change is obvious and cannot be ignored.

No. Inertia is an intrinsic property of an object, which is related only to its mass, not to its state of motion and velocity.

Inertia is only related to the mass of the moving object, the greater the mass, the greater the inertia, independent of the velocity.

Without gravity, you won't be able to shoot, and the basketball will fly up to the sky, and it will fly all the way up, because there is no gravity to make him fall to the ground, and humans will not dare to jump, and if you jump, you will never return to the ground, unless someone helps you, and there is something worse, and the air will become thinner and thinner, until there is not enough oxygen, and humanity will become extinct because it cannot breathe.

Without inertia, it's a big problem, because inertia is the dumber thing that objects move, and the people before us didn't explain exactly that there is no inertia, and there is no inertia, and in fact many of the laws of physics are wrong, like in a vacuum, under inertia, if you apply force to an object, it will move forever, and in the absence of inertia, you have to keep exerting force on it to keep it moving, so we have to work harder on everything, and the car needs more power to move forward, and every step it takes is like it's just starting out, and it takes a lot of force Instead of just having to overcome air resistance after starting now, and then a person can't stand on a car because he can't stand still, and his feet will be rubbed and he will fall, and you won't dare to jump on the ground, and if you jump, you'll fall far from the starting point, because the earth will turn again, and you'll hit a cliff or a wall, and jumping will become an extreme sport.

If the inertia and gravity disappear at the same time, then you don't shoot the basketball, and of course you don't shoot it, and you throw it like a box, and the basketball moves one square and stops in mid-air, because there's no gravity, because there's no inertia, and it's not going to go any further, and you're living in a world where objects are floating all over the place.

According to Newton's first law, if all the external forces on a moving object disappear at the same time, it means that the force on the object is zero, so the object will move in a uniform linear motion Option c is correct, a, b, and d are false

Therefore, C

(1) The property of an object that remains at rest or in a state of uniform linear motion is called 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.

2) When the external force acting on the object is zero, the inertia is manifested by the fact that the object keeps its state of motion unchanged, that is, it remains stationary or moves 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 greater inertia, and the object with greater acceleration has 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.

When an object is thrown, the inertia maintains its original state of motion, i.e., the embodiment of inertia in motion in a straight line.

The object will fall, that is, the vertical direction of the free fall motion is the action of gravity, which has nothing to do with inertia, not the result of inertia.

Therefore, the whole object is in flat motion, and the inertia does not change the direction of motion from the perspective of the sub-motion of the motion, and the combined motion is not the only effect of inertia, and gravity and resistance should be considered.

Your concept is not confused by one or two points, the object that is thrown out, the lack of inertia? Inertia is a property, and it is only related to mass, as long as the mass is still in inertia. When you're descending, gravity changes the state of motion, not inertia.

It is the effect of the object to maintain its original state of motion, whether this state of motion is stationary, translational, or rotating. That is to say, if it is not subjected to external forces, the moving object will always be in motion, and the stationary object will always be stationary. If you throw something horizontally, you will have a horizontal muzzle velocity when you get out of your hand.

Due to air resistance, the horizontal velocity will become smaller and smaller. Due to gravity, the object falls down, so the thrown thing moves in a parabolic motion. If there is no air resistance and gravity, the object will continue to move at a horizontal velocity.

Because we are surrounded by various forces, objects are thrown out and fall because of the gravitational pull of the earth, so they will fall down. In a vacuum, where there is no force, such as in space, if a thrust is applied to an object, then the object will always move away in the direction of that force.

Inertia is just a concept. The object moves in one direction and does not experience friction and does not stop. When the friction force is applied, the velocity is reduced by acceleration of a = f m.

Inertia is not without, so your premise is wrong, and therefore the conclusion is clearly wrong.

The lack of inertia leads to a direct descent because the object has gravity and drag, and inertia is only a property of the object itself.

But inertia is a property of an object itself, and it is not out of reach.
