Placing two figures one above the other and allow them along with their captions to fit on the same page. Ideally the figures will fit the entire page

Question

Is there a way to make the two figures that I have included in my document to be placed on the same page

So far I see the following:

The code I have written so far is this:

\begin{figure}
    \centering
    \includegraphics[width = \textwidth]{W.png}
    \caption{ ksd fxk sdkjf nksdzkulvskjzvlkzxsdlvsdlj. sdflkjznscfv dlk jnvl dfzlvxjkcnlk vndflkj. jnskjlnsdljkfn klkjsndflkjnsddlfk fsklj fklsjdnz flkjzskl sdlkj fnzsdkjlfnlksjznf lkjsdznfjkndflzxkj nlky}
    \label{fig:W}
\end{figure}
\begin{figure}
    \centering
    \includegraphics[width = \textwidth]{U.png}
    \caption{ksd fxk sdkjf nksdzkulvskjzvlkzxsdlvsdlj. sdflkjznscfv dlk jnvl dfzlvxjkcnlk vndflkj. jnskjlnsdljkfn klkjsndflkjnsddlfk fsklj fklsjdnz flkjzskl sdlkj fnzsdkjlfnlksjznf lkjsdznfjkndflzxkj nlky \cite{halle1981ionization}. }
    \label{fig:U}
\end{figure}

I put nonsense in the captions because I will edit it later.

Ideally I would like to force overleaf to place the two figures on one page and the two figures combined with their captions should fill the entire page. Is there a way to do this?

Possible way is to put inages into \vbox and type inside of box: \makeatletter\def@captype{table} — ElGatoGris, Aug 13 '21 at 13:15
Remove the lines 6 to 9 (\end{figure} \begin{figure} \centering ), but probably you must also reduce the size of the images. — Fran, Aug 13 '21 at 13:39
Is there a way that latex can adjust the shapes automatically so that both image sizes are adjusted so that they both fit fully inside the page along with their captions? — DJA, Aug 13 '21 at 13:43
Instead of defining the width, you can define the height of the images. — C. Peters, Aug 13 '21 at 14:12
I could mention that two [p] floats can use 100% of a page whereas [t] can only use about 70% (\topfraction) or a [t] and a [b] for 80% (\textfraction), but your floats are too big either way. — John Kormylo, Aug 13 '21 at 14:51

This scales both images to the same width so as to fit them into the available space.

\documentclass{article}
\usepackage{showframe}
\usepackage{graphicx}
\usepackage{pgfmath}
\begin{document}
\begin{figure}[p]
    \setbox0=\vbox{\caption{ ksd fxk sdkjf nksdzkulvskjzvlkzxsdlvsdlj. sdflkjznscfv dlk jnvl dfzlvxjkcnlk vndflkj. jnskjlnsdljkfn klkjsndflkjnsddlfk fsklj fklsjdnz flkjzskl sdlkj fnzsdkjlfnlksjznf lkjsdznfjkndflzxkj nlky}\label{fig:W}}% labels should go inside saveboxes (local @currentlabel)
    \setbox1=\vbox{\caption{ksd fxk sdkjf nksdzkulvskjzvlkzxsdlvsdlj. sdflkjznscfv dlk jnvl dfzlvxjkcnlk vndflkj. jnskjlnsdljkfn klkjsndflkjnsddlfk fsklj fklsjdnz flkjzskl sdlkj fnzsdkjlfnlksjznf lkjsdznfjkndflzxkj nlky \cite{halle1981ionization}. }\label{fig:U}}%
    \setbox2=\vbox{\includegraphics[width = \textwidth]{example-image-a}
      \includegraphics[width = \textwidth]{example-image-b}}%
    \edef\temp{\the\dimexpr \textheight-\floatsep-\ht0-\dp0-\ht1-\dp1}% available height
    \ifdim \ht2<\temp 
      \def\scale{1.0}%
    \else
      \pgfmathsetmacro{\scale}{\temp/\ht2}% cannot use \dimen0
    \fi
    \centering
    \includegraphics[width = \scale\textwidth]{example-image-a}
    \unvbox0
    \vskip\floatsep
    \includegraphics[width = \scale\textwidth]{example-image-b}
    \unvbox1
\end{figure}
\end{document}
