What is centrifugal force?

What is centrifugal force?

• A. Forces a body away from the center
• B. Forces a body toward the center
• C. Opposes motion in the direction of travel
• D. Is the friction that resists motion

Answer: (A)

Centrifugal force is the outward push you perceive in a rotating system. It appears in the rotating frame as if something is acting away from the center, explaining why objects feel pressed outward when a vehicle or seat rotates. In reality, there’s no real force pushing outward in an inertial frame. Your body tends to continue in a straight line due to inertia, while the inward centripetal force from the car, seat, or track bends your path toward the center. The outward sensation is a convenient way to describe that effect from within the rotating frame, with magnitude m v^2 / r and direction away from the center. So the outward push describes centrifugal force, while the actual inward force that keeps the motion circular is centripetal.
