Mathata a Rarollotsoeng Fisiks ea Motheo

3 Mathata le litharollo mabapi le equation ea Moment of inertia

1. Silindara e tiileng e na le radius ea 8 cm le boima ba 2 kg. Ho sa le joalo, bolo e tiileng e na le radius ea 5 cm le boima ba 4 kg. Haeba lintho tse peli li potoloha ka axis bohareng ba tsona, fumana karolelano ea motsotso oa inertia oa silindara le bolo.

Tse tsejoang:

Radius e tiileng ea silindara (r) = 8 cm = 0.08 m

Boima ba silindara e tiileng (m) = 2 kg

Radiyo ya bolo e tiileng (r) = 5 cm = 0.05 m

Boima ba bolo e tiileng (m) = 4 kg

Oa Batla: Papiso ea motsotso oa inertia oa silindara le bolo

1. Haeba lebelo la ntho le fetoha lebelo la yona la pele ka makgetlo a mahlano, jwale lebelo la ntho le fetoha ... lebelo la yona la pele.

Tse tsejoang:

Lebelo la pele = v

Lebelo la ho qetela = 5v

Mathata a 3 le litharollo mabapi le equation ea Speed

1. Koloi e tsamaea ho ea boroa ka limithara tse 100 ka motsotso o le mong ebe e retelehela bochabela ka limithara tse 120 ka metsotso e 0.5. Fumana lebelo le tloaelehileng la koloi.

Tse tsejoang:

Kakaretso ea sebaka = limithara tse 100 + limithara tse 120 = limithara tse 220

Kakaretso ea nako = motsotso o le 1 + metsotso e 0.5 = metsotso e 1.5 = metsotsoana e 90
