Why don't people on earth feel movement when the earth orbits?

This happens because we are all moving at a constant speed of 29 km/sec and we would only feel something if the speed changed, so it's a bit like being in an airliner at a steady 500 mph.
You would also feel it if the direction of your motion changed. It does change on the Earth's orbital path, but only about 1 degree in a day ... too little to feel. And you wouldn't feel it anyway because we are all in free-fall (see below).
It happens because the Sun attracts the Earth and everything in it with a force which exactly balances its acceleration towards the Sun according to Newton's laws of motion.
If you were alone in orbit round the Sun at the same distance and in the same nearly circular orbit, you would feel no force and you would also take a year to go round once. It's an effect known as 'free fall'.

Why dont you ever see the far side of the moon?
The Moon is "tidally locked" to the Earth, so it spins at the same speed as it orbits the Earth - once per 27 days. So we always see the same side of the Moon - the "near side".
