Weight is a force produced by which interaction?

Weight is defined as the force exerted on an object due to gravity. It is calculated using the formula ( W = mg ), where ( W ) represents weight, ( m ) represents mass, and ( g ) represents the acceleration due to gravity, which is essentially the gravitational field strength near the Earth's surface.

The mass of the airplane is a crucial factor because it determines how much gravitational force will act on it. The Earth's gravitational field provides the force that pulls the airplane toward the ground. So, when considering how weight is produced, the interaction between the mass of the airplane and the gravitational field of the Earth is what defines that force.

In contrast, other interactions mentioned—like wind friction or the lift generated by wings—do not define weight. Wind friction relates to drag forces acting against the aircraft but does not influence its weight. Air density and speed are factors affecting lift and drag but do not contribute to weight directly. Therefore, the correct response accurately captures the fundamental relationship that determines the weight of an object.
