What natural force pulls everything toward Earth?

What natural force pulls everything toward Earth?

• A. Lift
• B. Relative wind
• C. Gravity
• D. Leading edge

Answer: (C)

Gravity is the natural force that pulls masses toward each other, especially toward the Earth's center. It gives objects their weight and acts downward, which is why things fall when not supported. Lift is the aerodynamic force that acts upward on a wing as air moves over it, helping an aircraft overcome gravity. Relative wind describes how the air is moving relative to the aircraft, not a force itself. The leading edge is simply the front edge of a wing, not a force. So the force that pulls everything toward Earth is gravity.
