Galilean frame of reference

Galilean frame of reference is a frame of reference in which the principle of inertia is verified, i.e. any point body on which no force is exerted or on which the resultant of the forces is zero is in rectilinear translation motion uniform, or at rest. The history of Galilean theory dates back to the 17th century, when Galileo Galilei began to study the movements of celestial bodies using instruments such as the astronomical telescope. He discovered that celestial bodies followed simple laws of motion, independent of their position in space, and that these laws were independent of the observer. These discoveries led to the formulation of the first modern theory of mechanics, known as Galilean mechanics which describes how bodies move under known forces. A common example of using a Galilean frame is to describe the movements of celestial bodies in space, such as satellites and planets. It is also used to describe the movements of objects on Earth, such as ground vehicles and aircraft. It is important to note that in the context of modern physics, the Galilean frames of reference are no longer considered as absolute frames of reference but rather as approximate frames of reference because they do not take into account certain relativistic effects.
