- What is the relationship between the universal gravitational constant (G) and the acceleration due to gravity (g)?::The universal constant of gravitation (G) is an important variable frequently used in fields like orbital mechanics where it plays a role in calculating parameters such as orbital speed. Acceleration due to gravity (g) is also an important variable used to calculate properties like speed near the surface of a planet or other large body.
The value of G is a constant that should not change no matter where one is in the universe. The value of g, however, does vary for each planet, star, moon, or other large body based on its size and mass. These two gravitational parameters are related by the equation:
g=GMr2/r
where
g = acceleration due to gravity (m/s² or ft/s²)
G = universal gravitational constant (m³/kg/s² or ft³/slug/s²)
M = mass of the body (kg or slug)
r = radius of the body (m or ft)
- What is Aerospace engineering?::Aerospace engineering is the branch of engineering behind the design, construction and science of aircraft and spacecraft. It is broken into two major and overlapping branches: aeronautical engineering and astronautical engineering. The former deals with craft that stay within Earth\'s atmosphere, and the latter deals with craft that operate outside of Earth\'s atmosphere.
