N = ba ƙarfin yau da kullun
N sin θ = sashin kwance na ƙarfin al'ada
N cos θ = bangaren tsaye na ƙarfin al'ada
w = mg = nauyin motar
An tsara hanyar ne don a yi mata bandeji domin kawar da dogaro da gogayya.
Ana buƙatar ƙarfin kwance na raga, ɓangaren kwance na ƙarfin da aka saba amfani da shi ( N sin θ) , don ci gaba da tafiya a cikin da'ira a kusa da lanƙwasa.
Mun zaɓi axis na x a matsayin kwance da axis na y a matsayin tsaye, don haka hanzarta centripetal, aR, yana kan hanyar kwance. A cikin hanyar kwance, ƙarfin kawai shine ɓangaren kwance na ƙarfin al'ada (N zunubi θ), wanda ake buƙata don samar da hanzarin tsakiya. N sin θ = centripetal karfi.
