SUMMARY
The formula for the force vector parallel to the position vector r is defined as F_parallel = F * (r / |r|), where F is the force vector and r is the position vector. This relationship arises from the concept of projecting the force vector onto the direction of the position vector using the unit vector of r. The discussion clarifies that the multiplication of the force vector by the unit vector of r is essential for determining the component of the force that acts in the direction of r.
