Standards of Length, Mass, and Time: Newtonian Physics Lecture Series Lecture 1: Chapter 1 Section 1
Before we get into actual Physics, commentary must first be made about the foundations of all science, including physics. The fundamental basis for all physics is the concept of units. After all, when I say "The speed is 6", that is meaningless. Am I talking about m/s, km/hr., miles/hr, knots? Which units am I using? There is a system of measurement which has been around for centuries, but has been globally standardized for use in science since 1960 . This system is called the Système international from the French, who was the first to widely adopt the concept shortly after their Revolutionary War against Britain. The shorthand for this system is SI, and the fundamental units it uses for classical mechanics is the meter, the second, and the kilogram. There are other fundamental units in Classical Physics, but those deal with either electricity or waves, and since those are covered in their own separate semesters, I'll cover those fundam...
