  1. KOEFICIENT UPORA in GRAVITACIJSKI POSPEŠEK pri prostem padu

  2. Merjenje GRAVITACIJSKEGA POSPEŠKA z nitnim nihalom g = 9,89 ≈ 9.81

  3. Merjenje KOEFICIENTA UPORA • z vrvico izmerimo višino metališča (h = 8,60m) - sprožimo rafal posnetkov in žogico (h = 8,60m)

  4. s Photoshopom izmerimo razdaljo metališča – žogica in z izračunanim g ugotovimo čas padanja (zanemarimo upor) • na naslednjem posnetku razberemo razdaljo, času pa prištejemo 0.355s, kar predhodno izvršimo (rafal 30 – štopamo)

  5. Rezultati • g ≈ 9.9 m/s2 • grafa • c = 0.5 za obe žogici

  6. Pribor • meter • vrvica • dve žogici za namizni tenis (ena napolnjena) • fotoaparat • dva računalnika
