Šioje temoje nagrinėjamas kintamosios srovės generatoriaus veikimo principas, pagrįstas elektromagnetinės indukcijos reiškiniu. Aiškinama, kaip mechaninė energija paverčiama kintamąja elektros srove ir kaip vyksta periodiški elektrinio bei magnetinio laukų kitimai, vadinami elektromagnetiniais virpesiais.

Greitkelyje važiuojant dideliu greičiu, labai pavojinga staiga sukti.
Kūnui judant mažesnio spindulio lanku, įcentrinė jėga padidėja. Pavyzdžiui, kuo staigesnis kelio posūkis (t. y. kuo trumpesnis spindulys), tuo didesnė jėga turi veikti transporto priemonę posūkio centro kryptimi. Įcentrinės jėgos vaidmenį posūkyje atlieka trinties jėga. Jeigu ji per maža (esant slidžiai kelio dangai), transporto priemonė nulekia nuo kelio. Todėl posūkyje vairuotojai sumažina greitį.
