Concept of Friction Easy Explanation || Static & Dynamic Friction Numerical | Physics Class 11 Hindi @JK SMART LECTURE @engineering classes @JK SMART CLASSES LIVE
Hello Students i am Jaswinder kumar. Welcome back to my channel Jk smart classes and Jk engineering classes .in this video lecture i will focus on Concept of friction i details i will discuss following topics in this video

1.What is Friction 0:20
Frictional force opposes (impending or actual) relative motion between two surfaces in contact acts along the common tangent to the surface in contact.

Properties of frictional force (f)

Properties of frictional force (f)
β†’It is directed opposite to the relative motion
β†’It is parallel to the contact surfaces
β†’ It is proportional to the normal reaction
for N
β†’ It may or may not depend on the area of contact
