Moving low above the Earth’s surface (from 200 to 1000 km), the artificial satellite experiences a noticeable resistance from the atmosphere. How does its speed change: increases or decreases?
It would seem that under the influence of air resistance, the speed of the vehicle should decrease, as it happens, for example, with any car that rolls by inertia. But a satellite, unlike a car, has no solid support. Losing energy due to air resistance, it cannot maintain flight altitude and begins to approach the Earth. At the same time, due to its attraction, it accelerates and increases its speed.
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.
