There is a very interesting news once in the last few weeks Sukabumi Indonesia residents became excited by the dozens of stones neatly arranged in the middle of the river. Maybe we also often try to set their own small stones at home as collectibles.
But how does the concept of science explain it?
In art science this work is called the art of rock balancing. But there are some people who think that it is a mystical thing that happened with the river rock. Because with a sudden emergence of the stone is already neatly arranged.
According to the expert states that the art of composing the stone can be explained by classical physics. That is by using Newton's law, which says that the object will tend to be stationary or move at a steady pace if no force acts on it.
We've also seen people walking on ropes. The concept is also similar to how to arrange the stones that are eaten with a concept of balance, knowledge of stone texture and patience. People can certainly do rock balancing will definitely understand the characteristics of stone, geometry. Adjusting the position of the center point of the mass and the center of mass will affect the rock balanced for a long time.
The stones are arranged there is a small rock beneath and a boulder above. But if the stone form is as big and flat it will be easy and commonly done, rock balancing configuration not once so. The manufacturer must try repeatedly to obtain the most stable configuration by considering the force of gravity and friction. Whoever makes the position of the stone, of course, people are already very adept about the stone.
