buoyancydeals with any fluid, gases and liquids are both fluids, thus, aircraft must deal withbuoyancyto determine its ability to flow throw the fluid (air).
Three types of buoyancy are positive buoyancy, negative buoyancy, and neutral buoyancy. Positive buoyancy occurs when an object is lighter than the fluid it displaces, causing it to float. Negative buoyancy happens when an object is heavier than the fluid it displaces, causing it to sink. Neutral buoyancy is when an object has the same density as the fluid it displaces, resulting in it neither sinking nor floating.
Buoyancy is used by objects to float or rise in a fluid, such as water or air, due to a force acting in the opposite direction of gravity. To utilize buoyancy effectively, objects can be designed with specific shapes or materials to displace enough fluid to stay afloat. It is a fundamental principle in designing boats, submarines, and hot air balloons, among other applications.
We are merely testing the buoyancy of several types of ping pong balls.
No, air on its own cannot hold a person up. The lift required to overcome gravity and support a person's weight typically comes from other sources such as buoyancy (in the case of balloons or aircraft) or lift generated by wings (in the case of airplanes).
From Wikipedia: "If the object has exactly the same density as the liquid, then its buoyancy equals its weight. It will tend neither to sink nor float. An object with a higher average density than the fluid has less buoyancy than weight and it will sink. A ship floats because although it is made of steel which is more dense than water, it encloses a volume of air and the resulting shape has an average density less than that of the water."
An aerostat is a form of aircraft which derives its lift from buoyancy rather than from wings or rotors.
Bouyancy In case of an aircraft or a rocket, it would be called lift.
A nautilus uses gas-filled chambers in its shell to control its buoyancy.

The 4 main forces of flight are: drag, thrust, lift and weight
