How can I move the title of one chapter upwards on the page?

Question

I have this code:

    \documentclass[oneside]{book}
\begin{document}

\chapter{Example 1}

Text chapter 1

\chapter{Example 2}

Text chapter 2

\end{document}

Which gives me these two pages:

My question is: how can I move, for example, the title of chapter 2 upwards on the page while leaving the title of chapter 1 in the same place?

PS: My question is similar to this one but I would like to move the title of only one chapter upwards.

Welcome to TSE. I suggest that you type your question so that it is self-contained. — José Carlos Santos, Sep 17 '21 at 11:25
Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. — Community, Sep 17 '21 at 11:26

Much easier if you use the memoir class (a superset of book and report).

% upchapterprob.tex  SE 615713
%   \documentclass[oneside]{book}
   \documentclass[oneside]{memoir}
\begin{document}
\setlength{\textheight}{0.4\textheight} %% just for printing convenience   

\chapter{Example 1}

Text chapter 1

\addtolength{\beforechapskip}{-0.5in} % reduce space above title
\chapter{Example 2}
\addtolength{\beforechapskip}{0.5in} % restore space above title

Text chapter 2

\chapter{Example 3}

Text chapter 3

\end{document}


%%%% if using the book class instead of memoir then put the following,
%%%% less any typos, in the preamble. It is a redefinition of some book 
%%%% class code.
\newlength{\beforechapskip}
\setlength{\beforechapskip}{50pt}
\makeatletter
%% revised @makechapterhead
\renewcommand{@makechapterhead}[1]{%
  \vspace*{\beforechapskip}%
  {\parindent \z@ \raggedright \normalfont
   \ifnum \c@secnumdepth > \m@ne
     \if@mainmatter
       \huge\bfseries @chapapp\space \thechapter
       \par\nobreak
       \vskip 20\p@
     \fi
   \fi
   \interlinepenalty@M
   \Huge \bfseries #1\par\nobreak
   \vskip 40\p@
 }}
\makeatother
