PDF-1 The coefficient of kinetic friction

Friction k a is usually greater than the coefficient of static friction s b usually equals s c is usually smaller than s d equals the applied force that exceeds the maximum static force c 2 The purpos. Friction. Friction is a force that opposes the motion, or tendency of motion, of an object.. Friction is caused . mostly by . the . electromagnetic . interactions of particles within molecules at the surfaces of objects in contact. While these interactions can be rather complex, their combined effects can be reasonably approximated with a decent amount of consistency.. 2. Objectives. . Students must be able to. Utilize theory of dry friction. Describe . theory of dry friction. . Describe . physical meanings. of frictional effects. Describe and differentiate between . 93. Objectives. The student should be able to:. Prepare for the Brakes (A5) ASE certification test. . Explain kinetic energy and why it is so important to brake design. . Discuss mechanical advantage and how it relates to the braking system.. A force that opposes motion between two surfaces that are in contact.. Causes a moving object, such as a ball, to slow down and stop.. Occurs because the surface of any object is rough (microscopic hills and valleys). Friction. Unit 2 . Lesson 1. Friction. Friction is a part of everyday life, without it the world would be a very different place. Walking would not be possible, either would driving a car or playing sports. Even sitting on a stool would be difficult.. In-Class Activities. :. Check Homework, if any. Reading Quiz. Applications. . Characteristics of Dry Friction. . Problems Involving Dry Friction. Concept Quiz. Group Problem Solving. Attention Quiz. Friction is the resistance to the sliding, rolling, or flowing motion of an object due to its contact with another object. . When a moving object comes in contact with another object, friction is the opposing force that slows or stops the moving object. . What factors affect (the size of) friction?. Survey says:. Surface texture. Surface material. Surface area. Speed of slide. Mass. Weight. Angle of surface. Normal Force. What is the mathematical relationship between…...
