What would real life be like without friction?

If there is no friction, the clothes we wear will not hold in place, we will not be able to clamp some food when we clip it, and without friction our house will also slide off.

Everyone's opinion is different, and of course what I say is not necessarily accurate, I think that if there is no friction, real life will become a mess, and it is not conducive to people's survival. Moreover, the effect of force is mutual, and if it is forceful, there must be friction.

It's going to be a mess, and the kind of fire that people used to use won't work.

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

Personally, I don't think there's a way to live without friction, and if there's no friction in life, I don't think there's anything to live without.

If there is no friction, people and cars will not be able to move, I will not be able to hold Dong Chunju Minxi, car brakes will not be able to stop, etc.;

So the answer can be:

One: People walk without a trace.

Two: You can't hold things with your hands

What would the Earth be like if there was no friction -- If there was no friction, we wouldn't be able to walk. Because he could neither stand nor walk. For example, when walking on the ice, because of the ice slippery, I was tired and sweating after walking a short distance.

If there was no friction, the road would be smoother than ice, and people would only feel better if they fell to the ground. If there is no friction, the screws cannot be tightened, and the nails nailed to the wall will automatically loosen and fall. The tables and chairs at home will fall apart and will slide over and slide on the floor, and they will not be usable at all.

When pushing the table, when there is no thrust, if there is no friction, then the object has to move to the right, so the object has a tendency to move to the right, so the object will be subjected to a leftward static friction force that hinders this tendency of it.

For another example, in the process of transporting the goods upwards with the conveyor belt, if there is no friction, the goods should slide along the inclined plane, so the object has a tendency to slide down the inclined plane, so the conveyor belt has a static friction force along the upward slope of the goods, so as to hinder the movement trend of the goods to slide downward.

If there is no friction and medium resistance, the total amount of mechanical energy remains the same when only the mutual conversion of kinetic energy and potential energy occurs in the object.

That's the effect of no friction.

If there was no friction in this world.

There are a lot of problems in this world.

For example, in the absence of friction.

The tires of a car will not be able to grip the ground because there is no friction.

It can also become difficult for us to walk.

So friction is something like this in this world.

It's fast and slippery. Stop, stop.

Except for the upper left d, I will eat and not go to the wild, because it takes friction to bite the wild.

Friction is a physical force exerted on two surfaces when they come into contact with each other. Broadly speaking, objects are also subjected to frictional forces when moving in liquids and gases. As a metaphor, friction is also often used in everyday life to describe the forces that hinder progress.

Overview Friction is related to objects that rub against each other, so the description of friction in physics is not generalized and not as precise as other forces. In fact, one can only elicit the fundamental laws in mechanics if one ignores friction. Nevertheless, friction is a fact of the world.

Without friction, shoelaces cannot be fastened, and screws and nails cannot hold objects in place; Without friction, there would be neither traffic nor friction **The biggest difference within friction is the difference between static friction and other friction forces. Some people believe that static friction should not actually be counted as friction. The rest of the friction is related to dissipation

It causes the relative velocity of objects rubbing against each other to decrease, converting mechanical energy into heat energy and increasing entropy. The friction between solid surfaces is divided into sliding friction, rolling friction, rolling friction and rotational friction. In engineering, lubricants are used to reduce friction.

If two surfaces rubbing against each other are separated by a layer of liquid, then liquid friction can occur between them, and mixed friction can also occur if the liquid is not completely isolated. If a lubricant, liquid, or gas flows along a solid surface, its velocity is reduced by friction. The structure of the solid surface has less influence on this frictional force, the most important being the cross-sectional area of the fluid.

The reason for this is that there is friction not only at the interface between the fluid and the solid, but also between the different layers inside the fluid, and the flow velocity of the fluid is different depending on the distance from the solid surface. An object moving relative to a fluid is subjected to resistance. This resistance is in the opposite direction of its movement.

In the case of laminar flow this resistance is proportional to its velocity, and in turbulent flow this drag force is proportional to the square of its velocity. Sometimes an object is subjected to both drag and friction, such as a car that is in motion by both the resistance of the air and the rolling friction of its tires.
