Whakaoti i te e=1/2mv^2

$$e = 1 / 2 m v ^ { 2 }$$

Whakaoti mō m

$$m=\frac{2e}{v^{2}}$$

$$v\neq 0$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$\frac{1}{2}mv^{2}=e$$

He hanga arowhānui tō te whārite.

$$\frac{v^{2}}{2}m=e$$

Whakawehea ngā taha e rua ki te \frac{1}{2}v^{2}.

$$\frac{2\times \frac{v^{2}}{2}m}{v^{2}}=\frac{2e}{v^{2}}$$

Mā te whakawehe ki te \frac{1}{2}v^{2} ka wetekia te whakareanga ki te \frac{1}{2}v^{2}.

$$m=\frac{2e}{v^{2}}$$

Whakaoti mō v

$$v=\sqrt{\frac{2e}{m}}$$

$$v=-\sqrt{\frac{2e}{m}}\text{, }m>0$$
