Read the Wikipedia article on "ficticious force" for an explanation of the centrifugal force, and other ficticious forces. Briefly, it is a force that is introduced to maintain Newton's Second Law in a non-inertial (i.e., accelerating) reference frame. If the same object is observed from a non-accelerating reference frame, there is no need to introduce such ficticious forces.
Reactive centrifugal force is not the same thing as centrifugal force. Reactive centrifugal force is the reaction force. It is the reaction force reacting to a centripetal force.
Centrifugal force appears to increase with speed of rotation. Centrifugal force is a myth. It doesn't exist.
Centrifugal force is a measure of the opposite reaction of a centripetal force.
The centrifugal force is an apparent (ficticious) force, caused by a rotational movement. The amount of the apparent centrifugal force can be calculated by the same formula as the amount of the real centripetal force.
Centrifugal force is used in a roller coaster.
Centrifugal force is often confused with centripetal force.
Centrifugal force is an illusion, and doesn't really exist.
Centrifugal force/energy is the outward force associated with rotation.
Centrifugal force is a problem when turning at fast speeds.
Centrifugal force .
No.
A launched projectile is not an example of centrifugal force. It is an example of centripetal force.
