If the earth is spinning why do we need so many planes?

What if you want to go North or South?

you make my brain turn to shit

We spin at the same speed/which you already know/which is why we use airplanes

When you jump,you don't travel at a 800 mph difference from the ground....
.. Just like the moon

Lol how do you think my head is then?

You would need a pretty forceful machine to bring you down smartly, however somebody clever could invent one for us.

The earth sound, the atmosphere doesn't, does it?

Dumb

Everything on the earth is spinning at the same speed.

However the atmosphere doesn't spin, does it?

Of course it does and it does so because there is no friction where the atmosphere reaches space.

Yes, but is the atmosphere spinning?

But there should be friction at ground level, with the trees, mountains and buildings no less... sorry, you. Can't have it both ways... unless you work for NASA then you say whatever you want!

Coriolis effect only applies to sniper bullets...
Not to plane

At least according to spheretards ;)

Surely we could counteract that....geez we have been to the moon.

When you jump up, you have a velocity which is the velocity you had while spinning along with the earth.

Having a velocity while being pulled by a constant force results in a cyclic motion. In this case, earth's gravity is pulling on you.
Also, your path on this cyclic motion with the velocity you had before the jump eventually puts you back onto earth.

Another problem is that the atmosphere is both pushing you down and dragging you along towards the earth rotation.
It's actually rather complex.

But let's assume earth had no atmosphere. In such a case, you could have a catapult that would shoot you into the opposing direction of the earth's rotation just a few meters above earth with the perfect velocity such that you would stay always a few meters above the ground.
Unless my thinking went wrong, you could then actually use this as a means of travelling as far as you want around earth, just by waiting long enough.

Again, if my imagination does not fail me, one could imagine building a huge vacuum tube going all around earth, then accelerating things inside that tube in the opposite direction of earth's rotation just to the right velocity, such that the orbit is exactly within that vacuum ring/tube around earth.
That would be quite a low energy transportation method.

So if I launch a toy rocket straight up using a T to justijustify straight, the rocket will land to the west when it comes down on a clear day.

Kudos to the guy who questioned building a coil using the earths rotation.

If this was fact, they could easily have invented hovercars instead of what we use today.

Why cant we jump up really high over and over and just travel the world as it moves under us?

Apparently friction

No. Hovercars are supposed to defeat gravity. What i described is basically what satellites orbiting around earth do.
They are orbiting around earth because they were given the right velocity depending on their height and are constantly pulled by earth's gravity, resulting in a cyclic motion that would continue forever (almost).
Satellites do lose some energy slowly, especially low orbiting ones which are subject to a thin atmosphere still and require a little bit of boosting to stay in their orbit. But with no atmosphere at all, they would retain their orbit almost forever.

So we just need to find the right velocity to get my invention off the ground?

No. That is the easy part. The difficult part is building a vacuum tube all around earth.

What about vectra equilibrium?

If i told you i would have to kill you

Well so people currently think that the moment you leave the ground you are affected by the planets rotation and gravitational fields
Which is how they claim a plane flying at 500 mph manages to arrive at its destination when flying with the earth's rotation at 1040mph/kph don't remember which.

However under these principles a ball thrown 90 degrees into the air that takes 60 seconds to travel up and down that is affected the same way should land 7.8 miles away yet it doesnt.

Also any plane flying against the rotation of the planet is also pulled around by planetery rotation which is moving at 1040mph/kmh in the opposite direction yet your plane only flies at around 500 but you still get there .?

To extend on this it means. you are landing on an east-west runway in the states after flying from Europe ........science says you will make it even tho the rotation of the planet is faster than you ....realistically the plane would need to hit 1200 mph in order to have a 160 mph landing speed as the planets pulling you at 1040 in the opposite direction and at touchdown you would crash

There are many more examples but takes forever on my phone

Lol Why is that?

Surely we could use vectra equilibrium to make it work

Yes sir, just invent a craft to go up and wait for it to get to where your going, that the ticket. Not flying to it, let the world just spin to the place. Yes, take into the account the spin of the spin and then you can calculate the decent time. Don't got to high time different and that has to be calculated too.
