if you understand the principle of circular motion
u will find out that indeed, u will move around the earth,
unless u apply energy against the air and ur initial movement
(even if u lift the plane ...

樓主means that indeed[[tk_24]]

even when u "stop"
u are still moving

if he meant to stop perfectly
then there's no means to move around the earth

樓主的問題真係好"........."
架飛機停的話,其實只係個relative velocity =0(provided that the observer is on the earth or on the plane)...事實上架飛機係跟住個地球轉.
但如果你要講到架飛機係完全停晒,從外太空睇係見到佢唔郁的話...其實係地球ge人又會見到架飛機向後郁[[tk_29]]

跟住地球自轉

-終場ソ使者-

地球自轉同飛機行駛冇關係- -
但如果飛機有無限既能源,就一定會圍住地球(唔降落)
佢唔會飛上太空- -
