VLČEK „UBOMĶR * 086 01 Rokytov 132, SLOVAK REPUBLIC Abstract: The contributions to the study of motion made by many physicists, but especially those made by Galileo, Newton, Einstein, Vlcek. Inertial movement is straight line or quasi-circle. Who is right ? 1. Newton“s First Law of Motion An object at rest will remain at rest and an object in motion will continue to move in a straight line at constant speed forever unless some net external force acts to change this motion. ( Rest and motion are here measured with respect to same frame of reference such as the earth“s surface. ) Any frame of reference in which Newton“s first law is valid is called an Inertial Frame of Reference [1]. 2. Vlcek“s Generalized Law of Inertia Every mass ( atom, molelule, particle, body, vacuum ) persists in the status of the quasi-rest or quasi-uniform motion in a quasi-circle , as far as it the external forces do not force it to change its status. The inertial rotation of body consists of a quasi-uniform motion (in the quasi circles) of body's atoms. The inertial rotation of particle consists of a quasi-uniform motion (in the quasi-circles of subparticles - quarks, prequarks) [2]. 3. Nomenclature and Terminology Horizontal line is not horizontal straight line. Horizontal line is horizontal circle (quasi-circle) with radius R = 6378 km. Railway straight line is not straight line in geometry. Railway straight line is horizontal circle (quasicircle). A.Einstein [3] wrong write: Railway straight line is straight line in geometry (planimetry). Vertical line is straight line in geometry. Horizontal surface is horizontal sphere. Horizontal level is horizontal surface and horizontal sphere but is not horizontal plane. Geometrical plane is not sphere. Mathematical straight line in not horizontal curve. Plain trajectory is quasi-circle and not straight line. Ship trajectory is quasi-circle and not straight line. *Corresponding author: e-mail: lubovlcek@stonline.sk Conclusion On surface of Earth, the circle with radius R = 6378 km is a railway"straight line" = horizontal quasi-circle (in light of the origin of this term at Newton “s laboratory desk - a plane defined by the level = horizontal level = horizontal sphere is not geometrical plane). Let's have a real coordinates system firmly connected with a real laboratory on Earth, where all experiments testing the physical theories are performed. We know that this coordinates system moves around the Earth axis during an astronomical day i. e. it performs a quasi-circular motion. During the year it rotates around the Sun approximately in a quasi-circle together with the Earth. During 2.108 years it circulates in the quasi-circle around the center of the Galaxy. It performs a quasi-uniform motion in a quasi-circle together with the Sun. The Galaxy performs a quasi-uniform and quasi-circle motion around the center within the framework of metagalaxies of star clusters and our laboratory coordinates system on Earth together with it, etc. From the experimental testing of the law of inertia it is known that the body moves along the "plane" stated by a waterlevel, i. e. in fact it is not a straight-line uniform motion, but it is the motion in the circle of the Earth radius of R=6378 km. The space aeronautics show that space ships, Earth satellites and orbital laboratories move quasi-uniformly in almost a circle around the Earth. The atomic theory shows that the electrons and the nucleus circulate around the center of gravity of atom in approximate circles. The body rotating around its own axis (a flywheel) persists in this status. Similarly, the planets, stars, galaxies, molecules, nuclei and elementary particles rotate around their own axes. Since the uniform straight-line inertial motion cannot be achieved in a microworld, its place here is exclusively in the inertial quasi-circle motion.
