  What is the meaning of $f''(x)$?
  \begin{itemize}
  \pause
    \item the slope of $f'(x)$ at point $(x,f'(x))$
  \pause
    \item the rate of change of $f'(x)$
  \pause
    \item the rate of change of the rate of change of $f(x)$
  \end{itemize}

    The \emph{acceleration} is an example of a second derivative:
    \begin{itemize}
    \pause
      \item $s(t)$ is the position of an object (at time $t$) 
    \pause
      \item $v(t) = s'(t)$ is the speed (at time $t$) 
    \pause
      \item $a(t) = v'(t) = s''(t)$ is the acceleration (at time $t$) 
    \end{itemize}
