Once every student in his life hears a task from a teacher: "Come on, give examples of bodies moving relative to the Earth, as well as stationary bodies." Then the student has to think and remember the knowledge that the brain managed to learn in elementary school.
For all those who can not remember this knowledge, this article is written. But that is not all! More details about such a term as "movement relative to the Earth" will be discussed below. The simple answer to the question above is that the moving object relative to the Earth could be the Sun. After all, it is constantly in motion, passing its course through the sky. And stationary objects relative to the Earth are trees, numerous buildings and mountains.
What is motion relative to Earth?
Let's imagine that the line of the gyroscope is aimed at one or another star, which is motionless. Sothe line retains its own position in space, and its direction will always point to one star, with which it will move relative to the main point - the 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 the Earth's rotation exists. Later, the exact answer to the question posed will be given. Here are examples of bodies moving relative to the Earth.
Next example. Let the material point stand motionless in relation to the spaceship. In this case, the frame of reference will be the one that interacts with the space ship.
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=mg.
Denote m the mass of the material body and the acceleration (g) that is created by gravity.
The influence of the inertia of the body and its movement relative to the planet Earth is denoted by the letter F. In terms of indicators, it converges with the portable force of inertia. Also, the material point has its own frame of reference, which interacts with the space module.
What affects movement relative to the Earth?
It's easy enough to understand. The influence on the movement relative to the Earth is exerted only by the environment. Anyone can follow the changes. You can follow the movement relative to the planet Earth by watching the sunrise and sunset.
These same bodies could ever have beenput into action. They have a variant of rectilinear motion relative to the Earth. As evidence, we can cite Newton's law, which clearly indicates the calm state of the body, which is free from any external influence.
Now you can give examples of bodies moving relative to the Earth and prove their existence.
A certain point of mass m, located in the void approximately near the surface of the planet Earth, begins its fall. In other words, its movement relative to the planet, taking into account the insignificant height, passes in sufficient proximity to the rectilinear directions of the vertical (the flow of a thread with a special load). The forcing in a given conditional movement is regular (approximately), and its speed (at the initial moment) is classified by g. This example clearly shows the effect of a fictitious force on a point.
Examples of body movement:
What bodies move relative to the Earth? The answer to a similar question is quite simple and easy for those who at least roughly know astronomy or have ever come across space terms and concepts.
Give examples of bodies moving relative to the Earth: objects moving relative to the Earth can be both objects created by mankind and objects that existed in space long before the advent of science.
The moving bodies of human production include satellites, empty ships and space debris. To the moving bodies of the naturalorigin include comets, stars (including our Sun), meteorites, other planets and other cosmic bodies.
