Question

why do we see only one side of the moon always​

Answer 1

Only one side of the Moon is visible from Earth because the Moon rotates on its axis at the same rate that the Moon orbits the Earth – a situation known as synchronous rotation, or tidal locking. The Moon is directly illuminated by the Sun, and the cyclically varying viewing conditions cause the lunar phases.

We see only one side of moon because the rotation and the axis of moon is inclined towards earth
