Notes of friction
WebLecture Note Chapter 6 1. Overview: friction force Friction forces are categorized as either static or kinetic. The coefficient of static friction μs characterizes friction when no movement exists between the two surfaces in question, and the kinetic coefficient μk characterizes friction where motion occurs. s coefficient of static friction k coefficient of … WebMar 8, 2024 · FAQ on Friction Notes for Class 8 What is the frictional force? Frictional force is the force which opposes the relative motion when two objects are moving one over the other with their contact surfaces touching each other. There are several kinds of frictional force. If an object slides over the other then it is the case of sliding friction ...
