our earth will rotate yes one helicopter takeof in the air in one place after 3 hours later they land the healicopter the place will change
Answers
You can try this yourself. Let’s say that your jump can keep you in the air for 1 second. If you are in the mid-latitudes, the rotation of the Earth has a speed of 390 meters per second. So, jump, and see if you land 390 meters away from where you start.
You might observe that you don’t. That is because you are moving at 0 m/s relative to the ground and the air is moving close to that (depending on winds). For you to go 0 m/s relative to the ground to 390 m/s relative to the ground requires that you experience a force (and rather a strong one) to change your speed. It can’t come from the ground — the ground isn’t moving like that. It also can’t come from the air, which is also staying still. Your muscles aren’t strong enough to give you that much acceleration over a long enough period.
So that helicopter would have to shed the 390 m/s (or more — LA is somewhat southerly) it had from sitting on the ground from launch. And from the ground, that would look like the helicopter accelerating to an speed of 390 m/s (a speed that is above the speed of sound, and beyond what a helicopter can maintain).
Remember, the key to understanding physics is realizing that things like velocity are measured relative to other things. While there are some subtle effects from being on a rotating Earth, and it is very important for doing astronomy, for the most part we can treat the ground as stationary. Which means a helicopter needs to change speed to get to New York. (And pack a lot of fuel.)
Answer:
Yes, our Earth will rotate and revolve if we take an example for rotation the rotation of the rotor of a helicopter example of revolution is revolving around a place or object.
