Centrifugal force is best described as:

Centrifugal force is best described as:

• A. Force that pushes outward away from the center
• B. Force that pushes toward the center
• C. Force holding a vehicle on the curve
• D. Force due to gravity

Answer: (A)

Centripetal motion requires an inward pull toward the center to keep an object moving in a circle. In the rotating frame of the moving object, the inertia that wants to carry the object in a straight line manifests as an apparent push outward from the center—this is the centrifugal force. That outward description is the best way to capture what is felt or observed in such a rotating reference frame, which is why it’s chosen as the correct description. The true physical force pointing toward the center is the centripetal force that provides the inward acceleration needed to maintain the curve, while gravity is a separate force that acts downward and isn’t the outward push described by centrifugal force.
