Aerostatics
Aerostatics is the branch of physics that studies the behavior of gases at rest and their interactions with surrounding environments. It focuses on how buoyancy allows lighter-than-air objects, like balloons or airships, to float. The principle of buoyancy, explained by Archimedes, states that an object in a fluid experiences an upward force equal to the weight of the fluid it displaces. In essence, aerostatics encompasses the design and function of various airborne objects by understanding the balance between gravitational forces and the upward lift generated by gases like helium or hot air.

Aerostatics is the study of gases at rest, particularly how they interact with forces like gravity. It focuses on buoyancy, which is the upward force that allows objects, such as balloons or airships, to float in the air. This principle is based on Archimedes' principle: a body submerged in a fluid experiences a buoyant force equal to the weight of the fluid it displaces. Understanding aerostatics is essential for designing lighter-than-air vehicles and for applications in meteorology and environmental science, as it helps predict how gases behave in the atmosphere.
