For the unit of work. Work (W) is defined as force (F) multiplied by displacement (d). Force is mass (m) multiplied by acceleration (a).

Step 1: Analyze Question 1.
The question asks for the unit of work. Work ($W$) is defined as force ($F$) multiplied by displacement ($d$). Force is mass ($m$) multiplied by acceleration ($a$).

$$W = F \cdot d$$ $$F = m \cdot a$$

The unit of mass is kg. The unit of acceleration is $\text{ms}^{-2}$. So, the unit of force is $\text{kgms}^{-2}$.
The unit of displacement is m.
Therefore, the unit of work is $\text{kgms}^{-2} \cdot \text{m} = \text{kgm}^2\text{s}^{-2}$.
Comparing this with the given options:
