Which force is described as making your vehicle go straight on a curve?

• A. Friction
• B. Kinetic energy
• C. Centripetal force
• D. Gravity

Answer: (B)

When a car follows a curved road, it must change direction toward the curve’s center. That inward push is centripetal force. It isn’t a separate “mystery” force; it’s the net force toward the center that keeps the car moving in a circle, and friction between the tires and the road usually provides it. If there isn’t enough friction, the car can’t supply the needed inward pull and your tendency to go straight (inertia) wins, so you’d drift outward rather than follow the curve. Gravity acts downward and isn’t the sideways turning force on a flat curve, and kinetic energy is just motion energy, not a force that makes you turn. Therefore, centripetal force is the force behind following a curve, typically provided by friction.
