What happens if there is no friction on the ground?

If there is no friction on the ground, the world will become in a state of eternal motion, without stopping.

If there is no friction on the ground, everyone will not be able to move forward, or go backwards, and will have to stay put.

What would our lives be like if friction was gone? What will happen to the planet?

The world will be a mess, humans will not be able to walk properly, all kinds of vehicles will be suspended, you can see trees floating around, and even humans and forest beasts will all mix.

If the frictional force.

What happens when it suddenly disappears? First of all, you can't move an inch, for the simple reason that we all rely on the friction of the ground to move forward. Without friction, it is easy to fall, and it is difficult to stand up again.

No one in the moving person or car wants to stop, and it is impossible to turn a corner until there is a collision. Everything that could be moved on the ground slid low. In the end, they huddled together in a low-lying place, and no one wanted to leave.

The original stopped means of transport.

No matter how hard Ma Ji is, he can't start, and at most he skids. Theoretically, the plane can take off, but don't think about stopping when you fly, because there is no friction after landing. Fasteners such as screws and nuts rely on the principle of friction.

There is no friction, bridges, steel structure buildings.

Staggering due to slack nuts. Cars, trains, and machines fall apart instantly. So friction brings us a lot of trouble, and a lot of machinery needs lubrication. But it's more troublesome without friction!

We can't walk, because we can't stand on our feet, and we can't walk. Without friction, we would be on the road better.

The ice is still slippery, and I will be tired and out of breath after walking many distances. Without friction, the screws cannot be tightened, and the tables, chairs at home will fall apart and will slide around on the floor and become unusable. Without friction, the conveyor belt cannot transfer the goods.

Girls' makeup will slip off because there is no friction. We don't use the utensils we usually use for eating. We don't have to study anymore because of ballpoint pens.

Can't write. We are always on the ground, because we can't go up the stairs, and we can't do the elevator, because the conveyor shaft of the elevator can't move the elevator. We don't have any means of transportation.

But there are two sides to everything. There is no friction, there will be no bacteria on the teeth, dandruff will not appear on clothes and hair, and the rocket return capsule will not rub against the air and create high temperatures.

No friction means that the surface is smooth, everything in the world will be in a state of flow, and the objects on the earth will become the smallest unit of existence. If friction were gone, then all living beings living on Earth would behave in a way that we could not imagine! The wheels of the car must be gears, we must wear skates, we see people planting everywhere every day, the train must stick out many steel shovels to shovel the ground, otherwise it will not stop, the plane must reverse the engine when it lands, and without the force of Mocha, it is equivalent to no gravity, the terrible thing of time, everything is out of balance, there is no physical air at all, and human beings cannot survive!

If the friction disappears, then the big crack will float in the air, and there is not a lot of harm in Qingqi's words, and the impact on our lives is still great.

All objects can stop, cars are not allowed to drive, human beings are not equipped with a stool to walk, everything as long as it moves, there is no way to stop.

The world will become very chaotic, the car will not be able to brake, there will be a lot of car accidents, people will not be able to grasp something in the process of work or life because there is no friction.

When an object rolls on the surface of another object, the frictional force between the contact areas that blocks their relative motion is called sliding friction. The direction of sliding friction is reversed from the direction of relative motion. The magnitude of the sliding friction is related to the size of the non-slip level of the contact area and the size of the working pressure.

The higher the working pressure, the less smooth the contact area of the object, and the greater the sliding friction caused. For example, when you use a blackboard to erase a blackboard, the sliding friction caused by the two is the friction caused by the two.

What are the reasons for the scientific study of the size of sliding friction: Why do you use a spring scale to pull a wooden block to do a uniform linear fitness movement during the test? This is due to the fact that the spring scale measures the tensile force dimension rather than the friction dimension.

When the wood block is doing a uniform linear fitness movement, the tensile strength of the wood block in the horizontal direction and the friction force of the woodworking board on the wood block are a pair of balance.

According to the standard of two-force balance, the tensile force size should be the same as the friction force size. Therefore, the tensile dimension is measured, that is, the friction dimension is measured. Many tests have shown that the magnitude of sliding friction is only related to the size of the working pressure on the contact area and the non-slip level of the contact area.

The greater the working pressure, the less smooth the contact area, and the greater the sliding friction.

Sliding friction is the force that blocks the relative motion of objects touching each other, not necessarily the force that blocks the fitness movement of objects. That is, friction is not necessarily frictional resistance, it may also be the driving force that makes the object move well, and the "relative motion" to clearly block is based on the objects that touch each other as a reference. The "Object Fitness Movement" may be referenced to other objects.

For example, in daily life, the conveyor belt sends the goods from low to high, which is completed by the friction of the conveyor belt on the goods obliquely upward.

When studying specific problems in science, the "ideal" method is usually used for better simplification, such as one object being placed on the smooth surface of another object, and this "clean" means that if two objects are in relative motion, there is no friction between them.

The direction of the sliding friction force is always along the contact area and in the opposite direction of motion relative to the object. When the working pressure dimension of the object and the contact area are not smooth at the same level, the size of the sliding friction force is not related to the size of the total area of the contact area. The magnitude and direction of friction are irrelevant to the direction and velocity of the object's fitness movement.

The frictional force should be caused by the mutual attraction of the atoms, and they will rub against each other.

There are three necessary conditions for friction to occur, the first is that objects are in contact with each other. The second is the rough surface of the object. The third is friction. This creates friction.

Objects are in contact with each other, and then they are squeezed against each other, and the surface of the object is also very rough, which will produce friction.

Two objects rub against each other, so friction is generated, and friction is a very magical force.
