Lesson 1: Jismlarning ikki oʻlchamli harakati

Ikki oʻlchamli harakat: vektorlar. Turli xil trayektoriyalarni oʻzaro taqqoslash

1, 2 va 3 nomerli oʻyinchoq mashinalar quyida koʻrsatilgan trayektoriyalar bilan gorizontal yoʻnalishda harakatlanadi. 1- va 2- mashinalar harakatini 15, start text, m, end text lik qoyadan boshlaydi, oʻsha vaqtda 3-mashina 30, start text, m, end text lik qoyadan boshlaydi. Biz havo qarshiligini e’tiborga olmasligimiz mumkin.

Mashinalarning havoda boʻlgan vaqtlarini taqqoslang.
