What does the following mean -
[tex]\int \textbf{F} \cdot d \textbf{r}[/tex]
I know that its equal to work done. but i have problem in understanding it, what's the varibale. i am familiar with integrate cosxdx. what's is similar to dx in above equation. is it ds.
Now how can one get to this from above:
[tex]\frac{m}{2} \frac{d}{dt}(\textbf{v} \cdot \textbf{v}) dt[/tex]
[tex]\int \textbf{F} \cdot d \textbf{r}[/tex]
