Centrifugal force is defined as

• A. The force that makes water flow to move away from the center of rotation
• B. The force that pushes fluids toward the center
• C. The force that slows objects in rotation due to friction
• D. The force that holds fluids in place

Answer: (A)

Centrifugal force describes the outward push you observe in a spinning system. It’s the apparent force that makes water and other fluids tend to move away from the center of rotation when things rotate. This outward tendency comes from the fluid’s inertia—its desire to continue in a straight line—while the container spins around it, so the walls push the fluid outward to keep it moving in a circle. In an outside, non-rotating view, there’s actually a real inward force (centripetal) pulling the fluid toward the center; the outward “force” is what you notice in the rotating frame. That’s why fluids rise or push outward in a centrifuge or washing machine, rather than toward the center or remaining in place.
