If I want to use the dot notation for the time derivative of a vector is better (more common) to put the dot over the vector, or the other way around

1. `\dot{\vec{v}}`

![dot over vec](https://i.stack.imgur.com/j9ikL.png)
2. `\vec{\dot{v}}`

The first says the rate of change of the vector components, and the second says a vector made from the component rates.
