Maitiro Ekutenderera Kwepasi uye Kuchinja Kutenderera nekuchinja mafambiro maviri akakosha anogadzira "rhythm" yepasi. Kutenderera kutenderera kwepasi padivi payo, nepo kuchinja kutenderera kwepasi kutenderedza nyeredzi yaro—muSolar System, nyeredzi iyoyo iZuva. Mafambiro maviri aya anganzwika seari nyore, asi mashandiro ari shure kwawo anosanganisira fizikisi yakapfuma: simba rinokwevera pasi, angular momentum, torque, … Read more
