What is Friction? + example on an inclined plane – Physics – Mechanics – Forces

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!
