Once, every student in his life hears a task from a teacher: "Well, give examples of bodies moving relative to the Earth, as well as motionless bodies." Then the student has to think and remember the knowledge that the brain managed to learn in elementary school.
For all those who cannot remember this knowledge, this article is written. But that is not all! More details about a term such as "motion relative to the Earth" will be described below. The simple answer to the question above is that the sun can be a moving object relative to the Earth. After all, it is constantly in motion, passing its course through the firmament. And motionless objects relative to the Earth are trees, numerous buildings and mountains.
What is movement relative to the earth?
Imagine that the gyro line is aimed at a particular star that is stationary. So the line maintains its own position in space, and its direction will always point to one star, with which it will move relative to the main point - planet Earth. Such a visible movement of the axis of the gyroscope is the result of the rotation of the Earth for 24 hours. These data provide evidence that there is a rotation of the Earth. An exact answer to the question will be given later. We give examples of bodies moving relative to the Earth.
The following example. Let the material point stand motionless in relation to the spaceship. In this case, the reference system will be the one that interacts with the spacecraft.
The force from the mutual influence of bodies that are not in contact with our material body is considered to be the influence of the attraction of the planet Earth: P = m * g.
Let m denote the mass of the material body and the acceleration (g), which is created using gravity.
The influence of the inertia of the body and its movement relative to the planet Earth is indicated by the letter F. In terms of indicators, it converges with the portable force of inertia. Also, the material point has its own reference system, which interacts with the space module.
What affects the movement relative to the earth?
It is easy enough to understand. The effect on movement relative to the Earth is provided only by the environment. Anyone can follow the changes. The movement relative to the planet Earth can be traced by observing the sunrise and sunset.
These same bodies could ever be brought into action. They have a variant of rectilinear motion relative to the Earth. As proof, Newton's law can be cited, which clearly indicates the calm state of the body, which is free from any external influences.
Now you can give examples of bodies moving relative to the Earth and prove their existence.
Given example
A certain point of mass m, located in a void approximately near the surface of planet Earth, begins to fall. In other words, its movement relative to the planet, taking into account its insignificant height, takes place in sufficient proximity to the straight lines of the vertical (the flow of a thread with a special load). Forcing in a given conditional movement is regularly (approximately), and its speed (at the initial moment) is classified by g. In a similar example, the effect of a fictitious force on a point is clearly shown.
Examples of body motion:
What bodies are moving relative to the earth? The answer to such a question is quite simple and easy for those who at least roughly know astronomy or at least have ever encountered cosmic terms and concepts.
Give examples of bodies moving relative to the Earth: objects moving relative to the Earth can be both objects created by humanity and objects that existed in space long before the advent of science.
Moving bodies of human production include satellites, deserted ships and space debris. Moving bodies of natural origin include comets, stars (including our Sun), meteorites, other planets and other cosmic bodies.
