The centrifugal force in a rotating frame can be elegantly expressed in tensor form, where the tensor captures the dependence on angular velocity and mass. This formulation reveals that the force is symmetric and linear in position, acting radially outward from the axis of rotation. It vanishes precisely when the particle lies along the rotation axis, highlighting the geometric nature of fictitious forces in non-inertial frames.
