jism harakatini o'rganish tajribasi

amaliy ish №2: gorizontga burchak ostida otilgan jism harakatini o‘rganish i. maqsad jism gorizontga burchak ostida otib yuborilganda uning trayektoriyasi, uchish vaqti, maksimal balandligi hamda uchish masofasini aniqlash. ii. jihozlar – metall shar yoki kichik to‘p – proyektor yoki maxsus moslama (otish qurilmasi) – o‘lchov lenta yoki lineyka – kronometr – transportir – doska yoki tekislik iii. nazariy qism jism gorizontga burchak ostida v₀ tezlik bilan otib yuborilganda uning harakati ikki yo‘nalishda ko‘rib chiqiladi: ox yo‘nalishi: x = v₀·cosα·t oy yo‘nalishi: y = v₀·sinα·t – (g·t²)/2 bu yerda: – v₀ — boshlang‘ich tezlik – α — otish burchagi – g — erkin tushish tezlanishi (≈9.8 m/s²) – t — vaqt. maksimal balandlik: h = (v₀²·sin²α) / (2g) uchish vaqti: t …
