Some facts about the center of gravity mentioned here are very interesting, but we do not insist on their accuracy. We would rather encourage interest in its practical exploration.
The center of gravity and its functions are the essence of training, physical education and the development of the human being (the evolution). To study any physical exercise, any physical movements and positions, you must experimentally examine the center of gravity and the laws of its manifestations. The theoretical study is there completely useless and cannot replace the practical study of physical movements and positions.
Let us give you some questions about the center of gravity. Maybe these will better explain the problems we mean here.
1.Center of gravity in empty space: In the figure above, there is some wheel (A.), for example made of iron. Its center of gravity is inside (B.). But there is no matter here. So the center of gravity lies in the void (C.), which is outside and inside of this object (A.). Would it be here the center of gravity if there will not be this wheel?
2. Find the center of gravity and gravity axis: The above figure shows a material object (A.) that stands on the ground (B.) and is in balance. Where is its center of gravity? How does its gravity axis pass through it?
3. Find a common center of gravity: The above figure shows four material objects (A., B., C. D.). Where is their common center of gravity?
4. Find the center of gravity: The figure above shows the object (A.) falling to the ground (B.). Where is its center of gravity?
5. The relationship of two subjects: Imagine two material objects (A. and B.) that are placed side by side. Are these objects independent? Does each of these two subjects have its center of gravity? Imagine that the 7 billion people who live on this planet believe that these two objects are independent of each other, and that each has its own center of gravity. Are you of the same opinion?
6. Impact of object into a wall: The picture above shows a wall (A) and 4 objects (B., C., D., E.) and each is in a different state. The first object (B.) is at rest. He is motionless and his center of gravity is in the middle of this subject. The second object (C.) flies to the wall and its center of gravity is not in the center of the object, but at the back. The third object (D.) just hits the wall, and its center of gravity is deployed in the wall. The fourth object (E.) is deformed by the back impact and the center of gravity returns to the object.
7. Center of gravity: Did you ever think that the center of gravity is just only one?
