20.500.12556/RUL-69225 Gibanje pod vplivom močnega upora diplomsko delo Motion under the influence of large resistence V diplomskem delu je predstavljena analiza videoposnetkov prostega pada in vodoravnega meta s pomočjo hitre kamere in programske opreme Tracker, s katero lahko preverjamo fizikalne zakone. Teoretično je obdelan kvadratni zakon upora, ki ga izpeljemo iz zastojnega tlaka. Teoretično določim, kako se lega in hitrost telesa časovno spreminjata, ko je le-to pri gibanju podvrženo sili upora. Pri praktičnem delu je prikazana analiza posnetkov prostega pada in vodoravnega meta, kjer sta opazovani telesi krogla in balon, ki se gibljeta v vodi oz. skozi zrak. Tako preverim, ali velja kvadratni zakon upora tudi za predmete, ki so v primerjavi z medijem lahki. V programskem jeziku Fortran zapišem računalniški program, ki s pomočjo iteracije reši diferencialno enačbo za dvodimenzijski problem vodoravnega meta. In the diploma thesis, the motion of free fall and the projectile motion have been recorded using a high-speed camera and analysed with the Tracker software, a suitable tool for checking physical laws. A theoretical description of the drag law, is given. The change in position and velocity of a projectile, subjected to a large drag force, are determined theoretically. In the practical part, the analysis of the video clip of the free fall and the projectile motion, where the object are a plastic sphere moving through water and a balloon moving trough air, are shown. With this experiment, I check whether the drag law applies even to objects which are relatively light compared to the medium through which they move. A computer program which solves differential equations with iteration, written in the Fortran programming language, is used for computing the two-dimensional projectile motion. prosti pad videoposnetki true false false [D.
