TY - JOUR T1 - Pohyb po naklonenej rovine so silou trenia F_t a odporom prostredia F = kv^2 (pre stredoškolákov) A1 - Štubňa, Igor A1 - Štubňa, Martin JA - Obzory matematiky, fyziky a informatiky Y1 - 2015 VL - 44 IS - 2 SP - 47 EP - 50 SN - 1335-4981 N2 - The article shows the solution for motion of a body on an incline plane, while accounting for friction and air drag. We use two methods: 1) simple and approximate model by high school mathematics tools and 2) calculus (differential equation of motion) and show that they lead to qualitatively similar results. ER -
