This motion is called synchronous rotation. Yes the moon can be visible on opposite sides of the earth for two reasons. However its rotational speed is always the same. The earth rotates around its own axis once every twenty four hours.
The reason why only one side of the moon is visible from earth because the moon s gravity is tidaly locked by the earth s gravity. It s just that the amount of time it takes the moon to complete a revolution on its axis is the same it takes to circle our planet about 27 days. For starters the moon is not stuck in place with one side facing us. And because the moon s rotation upon its axis takes the same amount of time as the moon s revolution for orbiting around earth which is about 29 5 days.
The moon keeps the same face pointing towards the earth because its rate of spin is tidally locked so that it is synchronized with its rate of revolution the time needed to complete one orbit. The further away something is from the earth the further apart two earthbound observers can be to see it. Answered march 23 2018 author has 1 1k answers and 1 2m answer views. Our moon takes about 27 days to rotate around its own axis and 27 3 days to revolve around the earth.

As a result the same lunar hemisphere always faces earth. Our lunar companion rotates while it orbits earth. This is because the moon turns once on its axis in the same time that it circles the earth.

When we look at the moon we always see the same side. This results is your observation only one side can ever be seen from a specific point on earth.
