What Air Force is activated because of the mass of the airplane and works to pull an airplane to the ground?

The force activated due to the mass of the airplane that works to pull it to the ground is gravity. Gravity is a natural force that attracts two bodies with mass toward each other, and in the case of an airplane, it acts to pull the aircraft downward toward the Earth. The weight of the airplane, which is a product of its mass and the acceleration due to gravity, determines the force of gravity acting on it.
