Scientific Curiosity

One of my friends in lower sixth form said that the rotation of the Earth should be affecting our travel times. I was really confused, but now I'm actually curious. Does its rotation affect how long it takes us to get to or from somewhere, depending which way we're going?

[Marisa Fan]

Actually yes when you time travel to say a month ago the earth will be in a different spot so you will die in space... wait i don't think... never mind

The only way it affects is that you fly from one place at night, fly 10h and when you arrive there is still night there (due to diffrent timezones you didn't "moved" in a time so much)

but yeah.. too big diffrence in time can cause some sickness

I'm not talking about gravity - I can see how I may have confused you. What I meant was the Earth's ROTATION. On its axis.

Perhaps relatively speaking if you are in orbit.

No, it does not.

If the world is traveling at 600 MPH, then everying is already moving at 600 MPH. If you throw a ball into the air, it will come strait down as it is also traveling 600 MPH with the earths rotation.

I s2fg Spawn of Totoro is stalking me, he's been on like my past 5 conversations. 😯

I'm curious. The earth spins, and flight means travelling distance while the earth is spinning under you. If a plane flies in the opposite direction of the earths spin, does that mean the journey is shorter?

Or... if the plane is going in the same direction of the earth's spin, does the plane reach its destination?

[Sticky Honeybuns]

No it doesn't and it has to do with the frame of reference. We are on the thing(planet) that is moving so we are within that frame of reference. If you were to travel from the moon to earth then yes you would have to take into account of the earths rotation.

The best example is a fly in your car. The car is now the frame of reference. If the fly is flying around your car and you drove 10 miles, did the fly just fly 10 miles. No, because the fly only flew a few feet within the frame of reference which is the car.

Totoro already explained it. To expand upon it, we are all travelling at the same speed with the planet due to the gravity of the planet pulling us with it. If we weren't travelling along with it, we would get slingshotted into space.

What is this frame of reference malarkey? You start a 10 mile journey with a fly in your car. Ten miles away, and that fly is ten miles from the starting point as well. The fly has travelled 10 miles! That fly isn't going to leave the car and think "oh hell, I'm back where I started from."

Actually the fly would have flown 10 miles as there is nothing to tether or pull it along with the car. If it did not keep flying for the duration, it would either hit something or simply get blown out of the vehicle.

Read my last post but no for your answer too because you are within the same frame of reference.

The fly is inside the car.

I declare this frame of reference stuff to be bunk science.

Yes, but with no gravity tethering it to the vehicle, it would hit the rear windshield if it didn't keep up with the speed of the vehicle..
