The force that attracts a body toward its axis of rotation is called?

• A. Centrifugal Force
• B. Centripetal Force
• C. Center of Gravity
• D. Chord

Answer: (B)

When an object moves in a circle, it must be pulled toward the center of that circle to keep following the curved path. That inward pull is centripetal force. It’s not a separate outward force; rather, it’s the real net force toward the center produced by the appropriate combination of forces acting on the object (such as tension, lift, gravity, or friction), depending on the situation. The amount of inward force needed increases with speed and decreases with radius, following F = m v^2 / r (or F = m ω^2 r). In a helicopter rotor, each blade is kept on its circular path by this inward force toward the hub. Centrifugal force is a fictitious outward force that appears only when you analyze motion from a rotating reference frame, not the actual force causing the inward acceleration. Center of gravity refers to where the weight acts within the body, and a chord is simply a line segment connecting two points on a circle.
