LA MECÁNICA CLASICA, LA LUZ Y LOS TELESCOPIOS ASTRONÓMICOS

Modern physical science began with classical mechanics and astronomy. The earliest practitioners, such as galileo and newton, made important contributions both a physucists and as astromers.

La ciencia física moderna comenzó con la mecánica clásica y la astronomía. Los primeros profesionales, tales como Galileo y Newton, hicieron importantes contribuciones tanto a los físicos como a los astrónomos.

Hence, classical mechanics, the nature of light, and astronomical telescopes make fitting starting points for our study.

Por lo tanto, la mecánica clásica, la naturaleza de la luz, y los telescopios astronómicos hacen puntos de partida de ajuste para nuestro estudio.

Classical mechanics

In classical mechanics the most fundamental property of matter is mass. The fundamental frame of referece for describing the dinamycs of matter is an inertial frame, any frame, which is at rest or, at most moes at a constant velocity relative to the fixed starts. Since the starts are not truly fixed, we will later need to reconosider this definition; but for now we implicity assume that hence forth all physical laws are to be stated for such inertial frames.

Galileo discovered the first law of mechanics, and Descartes gave it a general formulation. (According to stillman drake) Galileo criticisms of the aristotlean viewpoint led him to shy away from stating general principles.)

The first law, or the principle of inertia, describes the innate resistance of matter to a change in its state of motion.

A body motion tends to remain in motion. Unless the body is acted upon by external forces, its momentum.
