Have you ever been stuck when trying to answer a mechanics question involving forces?
Maybe you were clueless on how to begin, or you got stuck at a certain point?

Well, this course is there to solve that problem: if you take this class till the end, and carry out all the exercises diligently, you will gain more than just the ability to solve mechanics problems. Hopefully, you will realize that Physics is actually pretty easy to handle: the patterns of thinking presented in this course are commonly used in many areas of physics, and could be very useful to you in your studies.

Class Structure:

This class presents a 5-step technique that can guide you through any physics problem involving force. It is structured in 3 sections.

The first three episodes contain a summary of the 5 steps and 2 solved examples. The goal of this first section is to for you to get an overview of the technique before diving into the details.

The second section consists in 6 lesson videos. The process of applying each step is presented in detail and in various situations. The conceptual and mathematical tools required to carry out each single step is also presented (1 step = 1 video + 1 extra video about the manipulation of vectors). You will learn how to draw a free body diagram, how to express a resultant force mathematically, how to manipulate vectors, when and how to apply Newton’s Laws etc…

The third section is your play-ground! You will find 8 exercises for you to train your skills in applying the 5-step technique. After giving you a chance to solve each question yourself, the presenter carries out a detailed correction on the white board. This section also contains a video lesson about mechanical friction forces.

The level of this class corresponds to the last years of High School Physics Programs. This makes it an ideal tool as support for the lessons you get at school, and to prepare any High School Diplomas in Physics, like for example IB Physics, A-Level Physics, AP Physics etc.

Enjoy!

Edouard Andre Reny was born in 1971 in Bordeaux, France. Long studies in sciences armed him a PhD in solid state chemistry which led him to a post doctorate contract at Hiroshima University, Japan. In his early thirties, he integrated a large water treatment corporation in The Netherlands as a senior researcher. A decade later, he decided to fly with his own wings by founding his own company, “Synaptic Machines”, that brought together his interests in sciences, his drive to share it with the world, and his passion and talent for music. Why not make a living with what one truly loves!

This coincided with the realisation that he was a damn good teacher. To support financially his bran new company, he started tutoring a few kids in their late teens to prepare for their I... See full profile
