It is related to the section RELATIVE MOTION
AS the moon is situated at long distance, with our naked eyes , we cant see its motion . MAny reasons are there for this. SO when we looks with naked eyes , it appers to be in rest at sky.
When we moves , there is a relative motion between us and the moon.
Resultant velocity of moon wrt. man = Velocity of man - Velocity of moon
= velocity of man - 0(as i told earlier) = velocity of man.
SO the velocity of moon wrt man = velocity of man
so we feel the moon is also moving with our speed.
