A significant part of aeronautical science is a branch of dynamics called aerodynamics, which deals with the motion of air and the way that it interacts with objects in motion, such as an aircraft.
When you pour a liquid from one container to another, the liquid takes the shape of the container. The volume of the liquid is the same. The properties that solids and liquids share are that they both have definite volume.
The properties we look at are shape, mass, and volume. Mass is the amount of matter an object has, and volume is the amount ofspace the matter takes up.Solids are easy to recognize. They have definite shape, mass, andvolume. Trees are solids.
