Whakaoti mō g
\left\{\begin{matrix}g=-\frac{v^{2}}{2}+\frac{F}{m}\text{, }&m\neq 0\\g\in \mathrm{R}\text{, }&F=0\text{ and }m=0\end{matrix}\right.
Whakaoti mō F
F=\frac{m\left(v^{2}+2g\right)}{2}
Tohaina
Kua tāruatia ki te papatopenga
mg+\frac{mv^{2}}{2}=F
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
mg=F-\frac{mv^{2}}{2}
Tangohia te \frac{mv^{2}}{2} mai i ngā taha e rua.
2mg=2F-mv^{2}
Whakareatia ngā taha e rua o te whārite ki te 2.
\frac{2mg}{2m}=\frac{2F-mv^{2}}{2m}
Whakawehea ngā taha e rua ki te 2m.
g=\frac{2F-mv^{2}}{2m}
Mā te whakawehe ki te 2m ka wetekia te whakareanga ki te 2m.
g=-\frac{v^{2}}{2}+\frac{F}{m}
Whakawehe -mv^{2}+2F ki te 2m.
