4. Copy the table below into your workbook and fill in the forces (Column B) for the given motions (Column A). The first one has been done for you.

\begin{tabular}{|l|l|}
\hline
Column A & Column B \\
\hline
\begin{tabular}{l}
Roller blades moving \\
forward
\end{tabular} & Pushing force \\
\hline
\begin{tabular}{l}
Hairdresser drying \\
your mum's hair with \\
the blow dryer
\end{tabular} & \\
\hline
\begin{tabular}{l}
Stretching an elastic \\
band
\end{tabular} & \\
\hline
Tying your shoelaces & \\
\hline
\end{tabular}



Answer :

Certainly! Let's fill in the table with the appropriate forces for each motion.

[tex]\[ \begin{tabular}{|l|l|} \hline \textbf{Column A} & \textbf{Column B} \\ \hline \begin{tabular}{l} Roller blades moving \\ forward \end{tabular} & Pushing force \\ \hline \begin{tabular}{l} Hairdresser drying \\ your mum's hair with \\ the blow dryer \end{tabular} & Blowing force \\ \hline \begin{tabular}{l} Stretching an elastic \\ band \end{tabular} & Tensile force \\ \hline Tying your shoelaces & Tension force \\ \hline \end{tabular} \][/tex]

Explanation of each entry:

1. Roller blades moving forward: The force involved here is a pushing force because you push against the ground to move forward.

2. Hairdresser drying your mum's hair with the blow dryer: The force involved here is a blowing force, as the blow dryer exerts a force by blowing air at a high velocity.

3. Stretching an elastic band: The force here is a tensile force, which refers to the force applied when you pull something apart, causing tension in the material.

4. Tying your shoelaces: The force involved here is tension force, which is the stress that results when you pull the laces taut to tie them.
