These notes are under construction! Various pages may contain helpful information but others are being developed.

The purpose of this notes is to help learners to understand the basic concepts of physics presented in basic introductory courses. Some of these notes include little algebra while others are presented with various calculus elements. The notes are the result of many years of experience teaching undergraduate students the three set of courses existing in most college and universities, introductory physics, algebra based physics, and calculus based physics.


There are two groups of educators/professionals to whom credit is due: physics textbooks authors, and JavaScript developers. During the years that I have expended teaching the subject many physics textbooks have been consulted or followed in those classes. Their input is invaluable in helping me to enhance the understanding of the different topics. From the JavaScript corner, the code used here is based on codes presented at and tutorials at In particular, I would like to mention where the website author has developed key elements that boost the flexibility of website interactions.
