This equation computes the Vector Norm, the positive length, of a vector from the Euclidean three space x,y,z components of the vector.

Inputs

• `v_x` - the x-component of the vector, `vecv`
• `v_y` - the y-component of the vector, `vecv`
• `v_z` - the z-component of the vector, `vecv`

Usage

There all kinds of vectors applied in physics for forces, positions, velocities, acceleration, etc. The position vector, often represented by `rvec` can be decomposed into its components parallel to the Euclidean three-space axes:  `vecr = r_xrhati + r_yhatj + r_zhatk`

Similarly, a velocity vector could be decomposed into its Euclidean components as:  `vecv = v_xrhati + v_yhatj + v_zhatk`
