Pri poučevanju fizike so naloge, pri katerih so grafične odvisnosti ključne za rešitev naloge, dokaj redke. Čeprav takšne naloge zahtevajo od učencev dodatna znanja, so pri nekaterih učencih zaželene. Zato je predstavljen primer obravnave naloge, kjer je s pomočjo grafa časovne odvisnosti sil v podporah mostu natančno določen način vožnje tovornjaka. Naloga je nadgrajena s primerom določanja pospeška kroglice med kotaljenjem po klancu. Sprva teoretično izpeljane zakonitosti so na koncu eksperimentalno preverjene in potrjene z meritvami video analize.
Abstract
Inquiry-Based Learning Using Hydrogels
Physics tasks in which graphical dependencies are crucial for finding a solution are quite rare. Although such tasks require additional knowledge from the pupils, some nevertheless ask for them. Because of that, this article presents a task in which the type of truck movement over a bridge is precisely determined by means of graphical dependencies of the forces acting on the bridge supports. The task is upgraded with an example of determining the acceleration of a ball while rolling down a slope. In the end, the theoretically derived equations are experimentally verified and confirmed by video analysis measurements.
