rotational kinematics - The Earth is spinning, so why don't we jump and land on a different location?


I know there are similar questions on StackExchange but I think it is different and detailed.


The earth is spinning 465 meters/second so why don't we jump and land on a different location?


I googled about this question and I got some answers:



  1. When we jump, we (and the atmosphere itself) also spin along with the earth so we don't land at a different location. (But why we are also spinning along with earth ?)


  2. The earth is so big and we are very small relative to earth so the tiny jump won't make any difference.


But according to answer 1, We are also spinning with the earth. But the question is, "why are we also spinning along with earth" ??


Regarding the answer 2, it won't make any difference but logically it doesn't make sense or I just don't understand it.


Here is the followup question,


"When we jump why don't we thrown out of earth due to centrifugal force of the spinning earth ??"


Please provide some detailed answer to these questions. With logic if possible.


This phenomenon is not possible I know, but even if it exists, then traveling will be so easy, we just have to hang on space (with help of helicopter etc.. ) and we can travel the whole world in 24 hours :D

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
