How can a butterfly fly inside a high speed Moving train?
So long as the train does not accelerate or decellerate (speed up or slow down), the inertia of the butterfly means that it will fly the same as it would anywhere else. This is because the air inside the train is travelling at the same speed as the butterfly (and also everything else in the train), so the butterfly feels as if it is not moving very fast at all. Relative to you and all the passengers in the train, the butterfly is flying normally. Relative to someone outside, watching the train speed by, the butterfly is moving very fast. Just think: The earth is travelling at over 100 000 km per hour as it orbits the sun, and it takes you, me, butterlies, and everything else with it. We all have inertia together, and travelling at the same speed, so it feels like we are not even moving. But actually we are! Speed/velocity is a relative concept. How far we are actually going depends on what you compare it with. My house is not moving relative to the ground, but relative to the sun it is
