Another difficulty is that students often consider the pseudo forces, e.g., the centrifugal force, as though they were real forces acting in an inertial reference frame.
The orlglnal formulathm of Newton’s third law is again under altack. Too many physicists-and not just undergraduates-fail to understand its core. … The answer most frequently given was: ‘The normal force the table exerts on the bottle’, a mistake I am sure I too would have made early in my career. ... It is not one action by which the Sun attracts Jupiter, and another by which Jupiter attracts the Sun; but it is one action by which the Sun and Jupiter mutually endeavour to come nearer together.
A body cannot experience a force in isolation. There cannot be a force on a body A without a second body B to exert the force. A cannot exert a force in isolation. A cannot exert a force unless there is another body B to exert a force on A. … At all moments of time the force A exerts on B is of exactly the same magnitude as the force B exerts on A. … neither force precedes the other force. … The data from all three studies support the hypothesis that the persistence of preconceptions concerning the third law may result from students’ general naive view of force as a property of single objects rather than as a relation between objects.

A recent engineering mathematics textbook states that ‘The centripetal force. . . [and]. . . the centrifugal force. . . are in equilibrium at each instant of the motion. We might be forgiven for thinking that this is what theologians call the invincible blindness that can only be rectified by prayer. Unfortunately, this view is widespread. For example, many students are likely to have absorbed uncritically the statement that the Earth’s attraction on the Moon is balanced by a centrifugal force.
for every action (force) in nature there is an equal and opposite reaction
This was attacked by Newton who tried to have the centripetal force on the planets (from gravitational interactions) be matched by the centrifugal force so there would be a balance of forces based on his third law of motion
