A vector representing the position of a point relative to a fixed origin
r\mathbf{r}r or OP\mathbf{OP}OP
r=(xy)\mathbf{r} = \begin{pmatrix} x \\ y \end{pmatrix}r=(xy)
r=(xyz)\mathbf{r} = \begin{pmatrix} x \\ y \\ z \end{pmatrix}r=xyz
AB=b−a\mathbf{AB} = \mathbf{b} - \mathbf{a}AB=b−a
∣r∣=x2+y2|\mathbf{r}| = \sqrt{x^2 + y^2}∣r∣=x2+y2
∣r∣=x2+y2+z2|\mathbf{r}| = \sqrt{x^2 + y^2 + z^2}∣r∣=x2+y2+z2
Velocity vector
Acceleration vector
Points that lie on the same straight line
