Zvinhu Zvinokurudzira zveAngular
Chinhu chinoita kufamba kwakatwasuka ine simba rinogona kuverengerwa uchishandisa fomura:
p = mv
Information :
p = momentum (chikamu chepasi rose ikirogiramu mita / yechipiri, chakapfupikiswa kg m/s)
m = huremu (chikamu chepasi rose ikirogiramu, kg yakapfupikiswa)
v = kumhanya (chikamu chepasi rose imita / sekondi, chakapfupikiswa m/s)
Huwandu hwemuviri mukufamba kwekutenderera hwakafanana nehuremu (m) mukufamba kwakatwasuka ndihwo nguva yekusaita basa (I). Huwandu hwemuviri mukufamba kwese kwakafanana nevelocity (v) mukufamba kwakatwasuka ndihwo kumhanya kwekonaSaka, chinhu chiri kutenderera chine simba rinogona kuverengerwa uchishandisa fomura:
Muenzaniso wezvinetso
1. Chidimbu ichi chine nguva yekusasimba kwe2 kg m2 ichitenderera ne angle velocity ye 2 rad/s. Tsvaga angular momentum ye particle!
Kukurukurirana
Zvinozivikanwa :
Nguva yekusashanda kwechikamu = 2 kg m2
Kumhanya kwekona = 2 rad/s
Akabvunzwa : angular momentum yechinhu!
Jawab :
Fomura simba rekona :
2. Chidimbu chine huremu hwe1 kg chinotenderera nekumhanya kwe2 rad/s. Radius yenzira yechidimbu i2 metres. Tsvaga angled momentum yechidimbu!
Kukurukurirana
Zvinozivikanwa kuti:
Huremu hwechinhu (m) = 1 kg
Kumhanya kwechikamu chepakati = 2 rad/s
Radiyo yenzira yezvikamu (r) = mamita maviri
Akabvunzwa: Kufamba kwechinhu chimwe chete (angular momentum)?
Mhinduro:
3. Chidimbu chine huremu hwe 0,5 gramu chinoita kufamba kwedenderedzwa ine kumhanya kwekona kunogara kuripo kwe2 rad s-1Kana nharaunda yenzira yechikamu ichi iri 10 cm, saka angled momentum yechikamu ichi...
A. 1 × 10-5 kg m2 /s
B. 2 × 10-5 kg m2 /s
C. 3 × 10-5 kg m2 /s
D. 4 × 10-5 kg m2 /s
E. 5 × 10-5 kg m2 /s
Kukurukurirana:
Kufamba Kwechinhu Chidiki:
L = (0,5 x 10)-5 kg m2)(2 rad/s) = 1 x 10-5 kg m2/s
