Centrifugal force is an apparent outward force during circular motion. It has been described as a reaction force according to Newton's third law. Which of the following statements is most likely to be correct regarding centrifugal force?
Correct answer: C. Centrifugal force always acts antiparallel to the centripetal force vector
- A. Centrifugal force exists only for uniform circular motion, not non-uniform circular motion.
- B. Centrifugal force exists only when tension or a normal force provides centripetal acceleration
- C. Centrifugal force always acts antiparallel to the centripetal force vector
- D. Centrifugal force is result of repulsive electrostatic interactions.
Explanation
The statement that centrifugal force always acts antiparallel to the centripetal force vector is likely to be correct because they are equal in magnitude and opposite in direction according to Newton's third law of motion. While the centripetal force is directed towards the center of the circular motion, the centrifugal force is an apparent outward force that emerges as a result of an object's inertia trying to continue in a straight line. Therefore, to maintain circular motion, the two forces act in opposite directions, with the centripetal force pulling the object towards the center and the centrifugal force pushing it away from the center.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
