Since the question does not specify what is being asked, I will summarize the interpretations of the states of motion:
- Accelerating to the right: Positive acceleration in the rightward direction.
- Fast speed: High velocity.
- Slow speed: Low velocity.
- Accelerating to the left: Negative acceleration in the rightward direction or positive acceleration in the leftward direction.
\[
\boxed{
\begin{align_}
\text{Accelerating to the right:} & \quad \text{Positive acceleration rightward} \\
\text{Fast speed:} & \quad \text{High velocity} \\
\text{Slow speed:} & \quad \text{Low velocity} \\
\text{Accelerating to the left:} & \quad \text{Negative acceleration rightward or positive leftward}
\end{align_}
}
