Matsalolin da aka Magance a fannin Fizik na Asali

Matsaloli 3 da mafita game da lissafin Moment of inertia

1. Silinda mai ƙarfi tana da radius na cm 8 da nauyin kilogiram 2. A halin yanzu, ƙwallon mai ƙarfi tana da radius na cm 5 da nauyin kilogiram 4. Idan abubuwa biyu suna juyawa da gatari ta tsakiyarsu, a tantance rabon lokacin inertia na silinda da ƙwallon.

Wanda aka sani:

Radius ɗin silinda mai ƙarfi (r) = 8 cm = 0.08 m

Nauyin silinda mai ƙarfi (m) = 2 kg

Radius mai ƙarfi na ƙwallon (r) = 5 cm = 0.05 m

Nauyin ƙwallon mai ƙarfi (m) = 4 kg

Ana so: Kwatanta lokacin inertia na silinda da ƙwallo

Matsaloli 3 da mafita game da daidaiton Sauri

1. Mota tana tafiya zuwa kudu na tsawon mita 100 cikin minti 1 sannan ta juya zuwa gabas mita 120 cikin minti 0.5. Ka tantance matsakaicin gudun motar.

Wanda aka sani:

Jimlar nisa = mita 100 + mita 120 = mita 220

Jimlar lokaci = minti 1 + minti 0.5 = minti 1.5 = daƙiƙa 90

Ana so: Matsakaicin gudu
