Can fly birds stay on a train?

Can't stay because of:

If it's an open-top train pulling coal, you can't stay because it's blown away by the wind.

If it's a bus, you still can't stay, because you didn't buy a ticket, you will be kicked off by the attendant...

I've thought about this question.

The person is stationary relative to the train carriage.

Flies fly relative to the air inside the train:

If the air inside the train is stationary relative to the carriage, i.e., the carriage is closed, then the flies will fly as if they were in a stationary house, and there is no need to chase the train.

If the air on the train is still relative to the ground, and the "carriage" is just a flat plate, then the fly will have to work hard, and it must fly hard to catch up with the train, otherwise it will fall behind! Or just land on the "carriage" and desperately grab the train with the peculiar suction cups on its feet, hehe, what a strong wind!

People have inertia when they stand in the car, so they will lean back when the car starts, but because there is friction on the soles of their feet, and people pull the rod, friction and tension give people a forward force, so that people have the opportunity to go forward with the car. Flies and birds are the same, they also have inertia, so they will also move backwards relative to the car the moment they start. But they are just as powerful to make them move forward, such as when they fly, and the resistance in the air will also give force, and once they have enough force, they will not have to exert themselves because of inertia.

Therefore, flies and birds will not hit the rear of the train so easily, otherwise, how can flies mix on the train, wouldn't the flies all die on the train?

When the train starts, it also gives the flies in the carriage a force to move forward. If the fly rests on the seat, it is pushed forward by the seat; If it's hovering in the air – don't forget, the fly in the air hovers because of the opposing force with the air. When the train starts, the carriage drives the air in the carriage forward, and the air also exerts a force on the flies to move forward.

Once the air in the train and carriage enters a state of constant progress, the flies on the seats and the flies in the air also begin to move at a uniform speed, that is, the effect of the so-called inertia.

No, it won't! It's like a balloon inside a train! It's the same to stay on the train too!

It can be said that it is a matter of speed reference frame, if the bird flies into the train from the outside, it should create on the train wall, but if it takes off from the train, it will not create

Hehe, I forgot all the problems in high school, it should be right.

He can sit on it like you.

It doesn't matter if it can speak or not.

Because flies are in the same way as people are in the train, the train is also walking when the flies fly.

A person walking on a train can also be faster than a train.

The train is the frame of reference, the flies fly in the train, and the air in the train is stationary relative to the train.

It's like a walking person is faster than the earth spins.

The starting speed is not the same.

Relative to the train, it may start to be stationary.

But then it was in motion relative to things outside the train.

So the question you ask can be said to be.

There is a premise for it to turn into the train.

It must be aggressive when the train is stationary.

Then or with it first reaches a certain speed, and is relatively stationary if the train has started to reach a certain speed.

It's dead and can't get in.

The question of relative velocity and absolute velocity, the relative velocity of any object with respect to itself is zero.

The absolute velocity of the fly is based on the train, and if the relative velocity is removed, the train is zero, and the fly is still negative?

Different. The vocal part of the fly is produced by the vibration of the wings.

100 million flies at the same time. Probably, perhaps, it seems, should, yes

What a fly that would be.

It's like an airplane haha.

If a fly hits a train at the speed of light, it can.

Hit a person very much have to slide a few hundred meters to stop, a fly. It's impossible to knock the train to a stop.

Live animals are now not allowed on trains, so it is impossible to bring birds. If you want to check it in, it's still realistic, but then you have to go through quarantine.

There are many things that can not be carried in railway transportation, and it is commonly said that the three products cannot be on the train, and the definition of the three products is flammable, explosive, and corrosive. However, there are many types of actual items, and the main items are the following 12 types.

Gun. Controlled knives, sharp weapons, blunt instruments (props with a finger blade length of more than 8 cm)**Items (detonators, explosives, firecrackers, etc.).

Oxidant. Compressed gas and liquefied gas (drifting snow, streamers, salutes, liquefied gas (small liquefied gas canisters used by donkey people)).

Natural items (phosphorus).

Burning items (sodium) in contact with water

Flammable liquids (gasoline, alcohol, banana water).

Flammable solids (magnesium bars).

Poisonous substances (poison gas).

Corrosive substances (sulfuric acid).

Radioactive materials (uranium, cobalt).

Can't bring, can't check, there are regulations on the railway, but, if you're not afraid of stuffing him, you can put it in your luggage, and you can carry it with you, don't let him run out or call it out (it is recommended not to carry).

Let it stand on the locomotive.

The train takes the birds as it does with the people

It's obvious. You're a stupid question.

What bird? I think so, I've seen people put cats in boxes and take them on the train.

Basically, every man has a belt.。。。

Because the train is now almost closed, the speed of the air in it is relatively stationary or very small to the speed of the car, and the resistance of the flies is basically the same as that outside. When all the windows of the train are fully open, it is difficult for flies to fly because of the high velocity of the airflow. If something lighter is placed on the table inside the carriage, such as books and newspapers, it will also be blown away.

The second question refers to 1, the air is stationary, so it can fly freely.

The spacecraft is flying close to the first cosmic speed, and the astronauts inside can move freely, for the same reason. The key point is that the flies (people) are in a sealed container, and the environment outside the container basically does not affect the inside!

Relatively stationary. I had it in junior high school physics class.

Flies are alive and can move in all directions, and of course flies also move with the train, because the air in the train moves forward due to inertia so the flies also move forward.
