Centrifugal force is
centripetal!
Centrifugal force is space reaction o curvilinear movement.
But space has one single force, elementary and compositional force, centripetal
force.
Is centrifugal force centripetal?
We consider a trial object, which executes a curvilinear movement around
a fixed point.
The curvilinear movement eccentrically polarizes space and the center
of centripetal force which is formed outside the curve, on the line of
vector ray. The mass of the object, speed of the movement and ray, determine
the intensity of polarization.
This is the force which pushes the object to the outside, to the center
of centripetal force and which "disappears" when their centers
coincides - forces are in balance.
Now, the object is imponderable, has rotation and its own centripetal
force (gravity) - moon.
Let's assume an interpretation, when the speed of the moon on the trajectory
is changed.
The increase of the speed equates the decrease of earth rotation, that
is, with decrease of terrestrial centripetal force.
The report of terrestrial and moon centripetal forces is changed, displacing
the centre of moon centripetal force to the outside, that is, the moon
gets a "centrifugal" force.
Upon speed decrease, the phenomena develop inversely.
Periodical inversion of the sense of centripetal force consists of oscillations
determining the stability of elliptic orbits.
This interpretation shows that in cosmos, bodies interact by their centripetal
forces - "gravitational".
