It is often discussed in physical educational journals. In the article some calculations are presented for shot put and hammer throw, the later being particularly interesting due to the success of Primož Kozmus. The work of the air drag is calculated and its influence on the range is estimated. Finaly, the trials are followed to connect the acceleration phase with the free motion phase giving some estimatesGibanje izstrelka je priljubljen zgled v učbenikih fizike. Pogosto se z njim ukvarjajo fizikalne poučevalske revije. Članek opiše račune pri metu krogle in metu kladiva. Slednji je zanimiv zaradi uspeha Primoža Kozmusa. Izračuna delo zračnega upora in oceni zmanjšanje dometa zaradi njega.
