Kuzungulira mkombero wozungulira - mphamvu ya mavuto ozungulira ndi mayankho

1. Galimoto yozungulira makona ozungulira. Kodi ngodya ya msewu womwe uli ndi makona ozungulira a mamita 60 ndi liwiro lopangidwa la 20 m/s ndi yotani? Tiyerekeze kuti palibe ayambitsenso pakati pa galimoto ndi msewu.

Anakonza

N= mphamvu yachibadwa

N tchimo θ = gawo lopingasa la mphamvu yachibadwa

N cos θ = gawo loyima la mphamvu yachibadwa

w = mg = ndi kulemera cha galimoto

Msewuwu wapangidwa kuti ukhale ndi magombe kuti uchepetse kudalira kukangana.

Mphamvu yopingasa yopingasa, gawo lopingasa la mphamvu yachibadwa (N tchimo θ), chofunika kuti galimoto iyende mozungulira mozungulira malo okhota.

Timasankha x-axis ngati yopingasa ndi y-axis ngati yoyima, kotero kuti kufulumira kwapakati,_R, ili motsatira njira yopingasa. Mu njira yopingasa, mphamvu yokhayo ndi gawo lopingasa la mphamvu yachibadwa (N tchimo θ), yofunikira kuti ipange kuthamanga kwapakatiN sin θ = mphamvu yapakati.

10. Kuyenda kwa matupi kumalumikizidwa ndi zingwe ndi ma pulleys
11. Matupi awiri omwe ali ndi kukula kofanana kwa kuthamanga
12. Kuzungulira makona osalala - mphamvu ya kayendedwe kozungulira
13. Kuzungulira mkombero wozungulira - mphamvu ya kuyenda kozungulira
14. Kuyenda kofanana mozungulira mopingasa
15. Mphamvu yapakati yozungulira yofanana
