Question

Можно ли считать движение ИСЗ по орбите вокруг Земли явлением инерции?

Answer 1

Нет. Величина скорости на орбите не меняется только по величине, а ее направление постоянно. Спутник движется под действием только силы притяжения Земли. Свободное падение. Падает, но не упадет благодаря скорости, направленной по касательной к орбите. Ответ: нет.

Answer 2

Can the movement of satellites in orbit around the Earth be considered an example of inertia?

The movement of satellites in orbit around the Earth can indeed be considered an example of inertia. Inertia is the tendency of an object to resist changes in its state of motion. Once a satellite is launched into space and placed in orbit around the Earth, it continues to move in a straight line at a constant speed unless acted upon by an external force. This is due to the satellite's inertia.

When a satellite is launched into space, it is given an initial velocity that allows it to achieve a stable orbit around the Earth. This initial velocity is carefully calculated to balance the gravitational force pulling the satellite towards the Earth and the centrifugal force pulling it away. As a result, the satellite maintains a constant speed and direction as it orbits the Earth.

The concept of inertia applies to the satellite's motion because, once it is set in motion, it will continue moving in a straight line at a constant speed unless acted upon by an external force. In the case of a satellite in orbit, the only significant force acting on it is the gravitational force from the Earth, which provides the centripetal force necessary to keep the satellite in orbit.

In summary, the movement of satellites in orbit around the Earth can be considered an example of inertia because once they are set in motion, they continue to move in a straight line at a constant speed unless acted upon by an external force, such as the gravitational force from the Earth
