Question

Е 4. Найди информацию.Найди в интернете (видеоролик для детей о Солнце), энциклопедиях инфор-мацию о том, почему планеты не разлетаются, а вращаются вокруг Солнца.​

Answer 1

Ответ:

Солнце притягивает к себе все окружающие его объекты с огромной силой, в том числе и планеты. Поэтому они не разлетаются в пространстве. Но планеты движутся с огромной скорость и возникает, так называемая, центробежная сила, которая пытается отбросить планету от Солнца.

Answer 2

Why Planets Don't Fly Apart and Instead Orbit the Sun

Planets in our solar system do not fly apart and instead orbit the Sun due to the combined effects of gravity and the initial conditions of the solar system. The force of gravity, which is the attraction between objects with mass, plays a crucial role in keeping planets in orbit around the Sun.

Gravity is a fundamental force of nature that acts between all objects with mass. It is responsible for the attraction between the Sun and the planets, as well as the motion of celestial bodies in the universe. In the case of our solar system, the Sun's gravitational pull keeps the planets in their orbits.

When the solar system formed about 4.6 billion years ago, a giant molecular cloud collapsed under its own gravity, giving rise to a rotating disk of gas and dust. The majority of the material in this disk accumulated at the center, forming the Sun, while the remaining material coalesced to form the planets.

As the planets formed, they inherited the angular momentum of the rotating disk. Angular momentum is a property of rotating objects and is conserved unless acted upon by an external force. The angular momentum of the rotating disk caused the material to form into a flattened disk shape, with the majority of the mass concentrated near the center (the Sun) and the planets forming in the outer regions.

The combination of gravity and the initial conditions of the solar system resulted in the planets orbiting the Sun instead of flying apart. The gravitational attraction between the Sun and the planets pulls them inward, while their initial angular momentum causes them to move tangentially, creating a balance between the inward pull of gravity and the outward motion of the planets. This balance allows the planets to maintain stable orbits around the Sun.

In summary, the reason why planets don't fly apart and instead orbit the Sun is due to the combined effects of gravity and the initial conditions of the solar system. The gravitational attraction between the Sun and the planets keeps them in orbit, while their initial angular momentum causes them to move tangentially, creating a balance between gravity and motion.
