Why do all cosmic bodies enter the Earth’s atmosphere at a speed no less than the second cosmic speed for the Earth?

A space body, even when it finds itself in the vicinity of the Earth with zero speed relative to it, will experience attraction from the Earth and, gradually increasing its speed, will fall on its surface. In this case, with a sufficient degree of accuracy, we can assume that this body falls from infinity. In accordance with the law of conservation of energy, it will have to acquire the same speed that would be required to send a body from the Earth into space, i.e., the second cosmic speed of 11.2 km / s.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
