# Illustration Orbital angular momentum and velocity of a mass during a circular motion

A body, which can be assumed to be point-shaped, has a mass $$m$$ and moves on a circular path with the tangential velocity $$\class{brown}{\boldsymbol{v}}$$. The circular path has the radius $$\boldsymbol{r}$$.
Due to the circular motion, the body has an orbit angular momentum $$\class{green}{\boldsymbol{L}}$$ that is perpendicular to the radius vector $$\boldsymbol{r}$$ and the tangential velocity $$\class{brown}{\boldsymbol{v}}$$.
