Butterflies and High-Speed Trains

Hi Friend, your answers are very meaningful and useful to me. keep it up. may i know your name, age, genter.

When the butterfly is flying inside the train it is flying relative to the train. So say a butterfly can fly at 1kmph, then when it is in the train it is flying 81kmph relative to the earth. When it is in the train it is not subject to air resistance because the train is moving with it but as soon as it flies outside of the train it encounters resistance from the air. At this point is is still going 81kmph, which is incredibly fast for a butterfly, and immediately begins to rapidly slow down. Because the train is still moving so fast it appeared that the butterfly zoomed off. What really happened is that the butterfly slowed down to about 1kmph incredibly quickly while the train sped away at 80kmph.

Good answer Thanks

I suspect the butterfly is now walking the tracks looking for its wings

and that's a GA from me, kinda like the way your mind works..

Do you have any difficulty walking up and down the corridors?
How does it feel when you put your head or hand out of the window?
If the butterfly is in a waiting room near the equator it's doing about 1000 mph relative to the centre of the earth; 67,000 mph (about 30 km per second) relative to the sun.

i couldn't think this is because of only the force of Air

it's only air that lifts the Airbus A380...

I think Einstein summed it up in his theory of Simple Relativity.

This is the same as if You went into the aisle and jumped up. You would come down in the same place not farther back. everything inside of the train is traveling at the same speed. Now if You jumped out the window You are no longer traveling at the same speed as the train and You would join the butterfly along side the tracks. DEAD!

is there any reason of gravitational force instead of Air Force.

No

Because the train has strong wind shield and the high velocity wind cannot pass thru the inside of the train to sweep off the butterfly.
