I want to label both equations separately, but I can't find the way. Instead, it displays only one tag for the equation.
My code looks like this:
\begin{equation}
m \vec{\gamma} = F(r, \theta, \dot{r}, \dot{\theta}, t)\mathbf{u_r}
\Longrightarrow
\begin{cases}
\mathbf{u_r} \Rightarrow m (\dddot{r}- r \ddot{\theta}^2) =
F(r, \theta, \dot{r}, \dot{\theta}, t) \\
\mathbf{u_\theta} \Rightarrow \frac{d}{dt}(r^2 \ddot{\theta}) = 0
\end{cases}
\end{equation}
And it displays what is shown in the picture:
