The Earth's gravity force pulls on all objects that are within a very wide area. The moon reacts to the Earth's gravity force by revolving around the Earth. When you weigh yourself, you are actually measuring the force of Earth's gravity on your body. The direction of your weight force is toward the Earth. The magnitude of your weight force is how heavy you are.
Airplanes have a weight force, too.
Even as they fly many feet above the Earth, their weight force is pulling them toward the Earth. Since they are so heavy, the magnitude of their weight force is very great. You are probably familiar with the lift force as well. You lift books off a desk. When a strong wind blows pieces of paper and other lightweight objects are lifted off the ground.
