The force exerted by the book on the surface is equal to its weight, which is given by F = m × g, where m is the mass of the book and g is the acceleration due to gravity (approximately 9.8 m/s²). Therefore, F = 0.5 kg × 9.8 m/s² = 4.9 N.

prinaša enega najbolj ključnih konceptov v naravoslovju: sile . Razumevanje sil, njihovega delovanja in izračunov je temelj za uspeh pri fiziki v osnovni šoli.
Če se predmet ne premakne, je rezultanta sil 0. To pomeni, da je sila trenja enako velika kot sila potiskanja, le v nasprotni smeri. 5. Kje najti dodatne brezplačne vaje (PDF)?

Pri vlečenju vrvi ekipa A vleče v levo s silo , ekipa B do vleče v desno s silo a) Kolikšna je rezultanta sil? b) V katero smer se bo premaknila vrv?
Dopolni prazna mesta.
Izberemo smer v levo za pozitivno. F r = 60 N (levo) – 45 N (desno) = 15 N v levo . Vrv se premika v levo. Can’t copy the link right now

) je nasprotno enaka teži, torej .c) Knjiga miruje, ker je vsota vseh sil nanjo enaka 0 (sili sta v ravnovesju ).
