People often refer to "the dark side of the moon", but there is no such thing. The sun shines on all sides of it in turn. However, there is a "far side of the moon" which is never seen from the earth. Over the eons, the gravitational forces of the earth have slowed down the moon's rotation about its axis until the rotational period exactly matches the revolution period about the earth.
You can see this effect by using two round objects such as softballs. Hold one of the balls stationary, to represent the earth. Now move the other ball around the "earth" without twisting your wrist. You will see that people on the "earth" would see all sides of the "moon". However, if you slowly spin the "moon" on its trip around the "earth", you will see that you can time it so only one side of the "moon" is ever seen from the "earth". That's why the features you see on the face of the moon never change.

The earth has rotation and revolution, but Moon does not have. It has only revolution and not rotation on its axis. Along the rovoluting earth, it goes to revolve on the Su.
Your next is wrong. (Don't believe that yo can not see the other side of the moon. It does not do any good to you.)
An Indian can not see the side of the moon which an American can not see. But American can see the photographs - as he has installed a lot of cameras there as well as in the orbit that sends photographs as and when he needs. (Let us say like that because the other bank of the river is green while we stand on this bank)

Only one side of the moon is ever visible to the entire Earth. This is because the friction of the surface of the moon with the Earths gravitational pull has slowed the moons rotation to a stop. So, the same face always points at the Earth.

only one side of the moon is seen because the time period of rotation and revolution around the earth are same
27 days
so an Indian can see a side of the moon which an american couldn't

The Moon has a bring about the international noted as the tidal result. It motives tides by employing coming up 2 bulges interior the sea (one close to the Moon, the different on the choice area of Earth). As Earth rotates below the bulges, friction tries to decelerate Earth's rotation. the quantity of braking is extremely small: each and every 40,000 years, our day gets a million 2d longer. even with the undeniable fact that, the Earth additionally has a tidal impression on the Moon. Earth being extra beneficial has a extra suitable tidal result. The Moon being smaller, feels the outcomes plenty quicker. To the element the place its rotation has been slowed down enought that it will continually recent a similar face to us (at that fee, the tidal result can no longer sluggish it down -- that's a challenge of equilibrium). So, there's a facet of the Moon that we see each and all of the time and a facet of the Moon that we by no potential get to work out (till we deliver a spacecraft). in case you have been on the Moon, in case you're on the area dealing with Earth, then you see Earth on your sky each and all of the time (it by no potential rises nor contraptions). in case you progression to the "some distance area", then you would not see Earth. by no potential. Ever. till you got here lower back to the "close to area", of direction.

I wud suggest carry out this simple experiment at home for very readily understanding the phenomenon.
Take a ping pong ball and paint half of it in red. Hold the red face of the ball towards u and mark E on the right side of the red face, and W on the left.
Now sit crosslegged in yr living room with the windiws to yr back the window represents the SUN.
At arms length right in front of u place the ball with the red face facing the window. U can see only the Red half from yr position.
Now pick the ball by left hand and place it at arms length on yr left hand side, without u turning or moving. Place the ball on the floor with red face of the ball facing the window. After placing it turn the ball from W to E(about its axis) by 90*. Now when u look at the ball u can see only the red face.
The ball has revolved around by 90*( from right ahead to yr left) and the ball was rotated about its axis also by 90*.
Try it again by keeping it right behind u, with red face facing the window. So the ball has revolved by 180 *( from right ahead to right behind U) Rotate the ball about its axis also by 180*. U will see the red face of the ball. What u have done is when the revolution was 180 * rotation was also 180*.
This is exactly what happens with MOON.
Its revolution speed around the earth and rotational speed about its axis is same. Hence only one face of moon visible to observer on earth.

Well thats because the moon makes a rotation movement on its own axis every 27 days, and is exactly the same time that makes an entire orbit arround the earth, so is making both movements at the same time and we dont even notice because we always see the same side.

Moon's self rotation time and going round the Earth time is same = 29 days.
When you tie a ball in a string and rotate by holding the string, you will get the effect.
Ball represent Moon and you are Earth.

we see the same side of the moon because the time taken by the earth and the moon to rotate and the time taken by the moon to revolve around the earth is nearly the same. hence we see the same face of the moon from one particular point.

Anyone can see the side of the moon furthest from the earth, as satellites have photographed it.
There is no way for anyone to see the side of the moon furthest from the earth, regardless of their location on the earth, unless they are using a satellite, or reference photos.
