Feynman diagrams are a graphical representation of the processes involved in particle physics reactions. This video is the first episode of a series of three that presents what are Feynman diagrams, how to understand and use them, and how to build them. In this episode you will learn what a Feynman diagrams is. We will use for this a well-known particle physics reaction as support, beta decay. Feynman diagrams are an insightful tool that puts to light the wonders of particle physics. The reactions occurring in particle physics are a marvel of processes involving the forces of nature (weak force, strong force and electromagnetic force). Writing these like a chemical reaction does not provide information about the processes involved, just what you start up with, and what you end up with. One can use the Quantum Chromodynamics (QCD) and Quantum Electrodynamics (EOD) to model quite well what is going on, but the mathematics involved is not for everyone! Instead, graphical representation of these reaction, invented by Richard Feynman, allow all to visualize the processes involved easily: Feynman diagrams. He introduced these originally as a graphical aid for visualizing and calculating interactions between electrons and photons. Today, Feynman diagrams are commonly used to depict all types of particle interactions. These videos are intended to help high school students with their physics studies as well as high school physics teachers wondering how to approach the topic with their students. **** Access to the Videos **** Introduction: Content review of the Feynman Diagram mini-series https://youtu.be/O9ihGuK53Ww Episode 2: Space, Time and Vertices.

Move a heavy object across a carpeted floor: at first, it is hard to get the object to move. Yet, once it is moving, it is easy to keep the motion going. Understand why that is just in a few minutes of video! This physics video tutorial provides a basic introduction into kinetic friction and static friction: Discover that there are two kinds of friction which are at work in such a situation: static friction and kinetic friction. Discover also how frictional forces are dependent on the normal force applied by the ground on the object. This relation links friction with the other forces acting on a body and provides you with the clues to solve physics problems where friction is involved. - - - - VIDEO CONTENT - - - - Today's episode of Physics Made Easy is a mechanics crash course on friction structured in two parts: first a lesson, which explain the origin of friction and how to express it mathematically. And second, a solved example: friction on an inclined plane. At the same time, this example shows you the 5 steps on how to solve these kind of problems: 1/ Draw a Free Body Diagram 2/ Define some axes 3/ Determine an expression of the Net Force on the body 4/ Apply Newton’s Laws 5/ Solve. - - - - A FULL COURSE! - - - - Explore further how to use these five steps to solve any physics problem that involve forces by taking an extensive course that will definitely lifts those blocks you might have with mechanics. This course contains straight-to-the-point lessons and tons of exercises for you to train on your new skills. This is how you can become a master in solving these kinds of physics questions: Learn and understand the 5-step technique, and solving these problems will become second nature to you!
