strong nuclear force

Remember, even if you weigh less because of a change in gravity’s force on your body, your body’s mass is still the same. As your body grows, you will have more mass, which also means you will weigh more. That’s because when you’re on the earth, the amount of gravity that pulls on you stays the same.

weight ( ) 1. The force with which an object near the Earth or another celestial body is attracted toward the center of the body by gravity. An object’s weight depends on its mass (the amount of matter it consists of) and the strength of the gravitational pull.

Weight is the force of gravity on an object. Weight depends on the strength of the gravitational field the object is in and the mass of the object. Mass is constant anywhere in the universe, whereas weight depends on the gravity where the object is present (Earth, the moon, Jupiter, etc.). …

The gravitational force between a mass and the Earth is the object’s weight. Mass is considered a measure of an object’s inertia, and its weight is the force exerted on the object in a gravitational field. On the surface of the Earth, the two forces are related by the acceleration due to gravity: Fg = mg.

The United States

The country has been physically invaded a few times – once during the War of 1812, once during the Mexican–American War, several times during the Mexican Border War, and once during World War II.

Without the American entry into World War II, it’s possible Japan would have consolidated its position of supremacy in East Asia and that the war in Europe could have dragged on for far longer than it did.
