I heard something new that realy makes you wander. If the earth is rotating as they say than how airplanes can go in straight line? If earth is moving under them they should land way off the desired destinacion… 😮 They are not connected to the earth so rotacion shouldnt apply to them, it applyes only to cars and runing animals but not on airplains and bierds… Also when you jump from baloon that is wery high up, you shouldnt fall straight down, if the earth is rotating it should move under you and you could newer fall on the same spot that you jumped over… 🫢
I cant beleave this newer came to my mind for entire life… 😵
If you’re in a moving car, and you toss something small straight up into the air, does it come straight back down to your hand, or way behind it?
This is a good start to explain it. Many of the posts here are also neglecting that the air around the earth is also moving along with the earth, but often at a different speed. It is not fixed in space.
For example, if you’ve ever paddled a canoe across a flowing river, you’ll either end up not across from the point you left from or you’ve steered the canoe as if you were intending to land upstream. This is because the water is pushing the canoe downstream.
Also, the comments (as if the time of this post) are all neglecting the point of reference.
An analogy on point of reference would be if you’re on a train, sitting at a table facing the rear of the train and the train is moving in the forward direction at a constant speed on a plain, if you drop an orange on the floor of the train, will it immediately roll to the back of the train?
In airplanes there is often a big difference between land speed and air speed. That is (one of the reasons) why the return trip is not the same duration when you travel in the east-west (or west-east) direction. The airplane is pushing against the airaround it whereas a car is pushing against the ground (Earth).
