Overview

Friction is a force that resists the relative motion of two surfaces in contact. It arises from the microscopic interactions between the irregularities on the surfaces. Friction plays a vital role in everyday life, from providing traction for walking to braking our cars. Friction has many effects and applications in everyday life, such as starting a fire, walking, braking, and wearing. In this course, you will learn about the following topics:* Types of friction: static friction, kinetic friction, rolling friction, and fluid friction.* Factors affecting friction: normal force, surface roughness, material properties, and lubrication.* Applications of friction.* Problem Solving Strategy.By the end of this course, you will be able to:Explain the concepts and phenomena of friction using examples and experiments.Solve problems involving friction using mathematical and graphical methods.Evaluate the advantages and disadvantages of friction in different contexts and scenarios.This course is suitable for anyone who is interested in learning about the basic principles of physics and engineering that govern the natural and artificial world. No prior knowledge of friction is required, but some familiarity with algebra, calculus, geometry, vector and fbd is recommended. The course will consist of lectures, quizzes, assignments, and interactive activities. You will also have the opportunity to interact with your instructor and fellow learners through online forums and discussions. The course duration is 2 weeks, with an estimated workload of 4 hours per week.
