y when u drop a piece of paper from 100m wont burnt coz of d friction but a space shuttle will when it enters d earth since d gravity acceleration is d same (9.8g)

It's not the acceleration, it's the speed. The shuttle hits the atmosphere travelling at 17,500mph, thus generating huge amounts of friction and therefore great heat. The paper doesn't.

In order to get that much friction you need speed. Paper will never fall fast enough except possibly if it fell from space. It doesn't have enough weight per surface area or density to travel fast enough to warm much in normal thick air. Things falling from space are falling much faster than a bullet.
