Join me on Coursera: https://www.coursera.org/learn/vector...Position Vectors in Cylindrical Coordinates. This is a unit vector in the outward (away from the $z$ -axis) direction. Unlike $\hat {z}$, it depends on your azimuthal angle. The position vector has no component in the tangential $\hat {\phi}$ direction.Another common convention for curvilinear coordinates is to use ρ for the spherical coordinate . r. We will not use ρ for the radial coordinate in spherical coordinates because we want to reserve it to represent charge or mass density. Some sources use r for both the axial distance in cylindrical coordinates and the radial distance in ...

Cylindrical coordinates Spherical coordinates are useful mostly for spherically symmetric situations. In problems involving symmetry about just one axis, cylindrical coordinates are used: The radius s: distance of P from the z axis.

The position vector, a vector which takes the origin to any point in $\mathbb{R}^3$, can be expressed in cylindrical coordinates as $$\vec{r}=r\vec{e}_r+z\vec{e}_z$$ but, if the basis of $T_P\mathbb{R}^3$ for a specific point $P$ is only used for vectors "attatched" at $P$ or a neighbourhood of $P$, why can we express a vector from the origin ...

The vector d! l does mean “ d! r ” = differential change in position.

A ball rolls outward so that its position is r = (0.1t3) m.The radius unit vector is defined such that the position vector $\underline{\mathrm{r}}$ can be written as $$\underline{\mathrm{r}}=r~\hat{\underline{r}}$$ That's what makes polar coordinates so useful. Sometimes we only care about things that point in the direction of the position vector, making the theta component ignorable.Figure 7.4.1 7.4. 1: In the normal-tangential coordinate system, the particle itself serves as the origin point.
