If the helicopter hangs in the air, if he would in 12 hours at the other end of the Earth?
The wonders of physics in our lives.
We live in an amazing world, where you have this strange illusion that explodes our brain. In particular, this applies to physics, which can surprise anyone. Especially those for whom the school she was not of interest. And for good reason. This science holds many interesting secrets of the universe. For example, we all know that our planet carries out a rotation around its own axis. What do you think, could the helicopter rose into the air and hovering at the same height, to be on the other side of the planet in ten hours?
If you don’t know physics, then you can give to this question is the wrong answer, mistakenly thinking that this is possible. But this answer is clearly wrong. The fact that according to the laws of physics for a helicopter ascending vertically upwards, is still on the surface of the Earth. As a result, the helicopter hovering at the same point in the sky, will move in the direction with the same velocity, which will spin the Earth.
Therefore, it is impossible to travel around the world, rising above the Ground and hovering in one place. In particular, you will not be able to do it, if theoretically to assume that you could jump up and hover in one place. Unfortunately, in this case, you also won’t be 12 hours on the other end of the planet. Alas, the laws of physics forbid it.
Even aircraft which fly at high altitude, almost tied to the Earth by the gravitational field of our planet. It is the gravitation of the Earth does not allow flying vehicles to hang in the sky in one place. Now, if gravity is not working on floating in the air helicopter, then he could, hovering in one place, find yourself in about ten hours elsewhere on the planet. But we know that no helicopters or planes is impossible. To reduce the effects of gravity on our planet, it is necessary to fly in space, which makes the design of conventional flying vehicles.
For example, in a moving train, if we jump in the car, despite the fact that the car is moving, landing in the same place, where did the jump. That is, despite the fact that we jumped up, turned in the air, we move out of inertia along with the train at the same rate. That’s why we don’t change its position when you jump in a moving train.
If you sit in the bus and it suddenly brakes sharply, you instinctively lean forward, in fact, continuing out of inertia motion with the same speed at which the bus was traveling before braking.
So the helicopter hanging in the air in one place can’t be 12 hours on the other end of the planet.
But if the helicopter found himself in space, he could partially realize such a scenario, finding himself in another place, using the natural rotation of the Earth.
