# Friction Types of Friction , Friction Numerical Video Lecture Physics Class 11 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)
→It is directed opposite to the relative motion
→It is parallel to the contact surfaces
→ It is proportional to the normal reaction
for N
→ It may or may not depend on the area of contact
