How Work Done is Calculated for Changing Direction?
This can be done using the line integral seen in vector calculus. You can define the work as
$$W=\int \vec{F}\cdot d\vec{r}$$
where $d\vec{r}$ depends on the parameterize curve and $\vec{F}$ can be a …

Why we take $k=1$ in $F=ma$?
The force was found to be proportional to the acceleration, not $ma$. This means that $F=ma$ with $m$ the constant of proportionality.
