ROLLING FRICTION , MOTION OF A CAR IN FLAT ROAD & BANKED ROAD # PHYSICS CLASS 12

CHAPTER : 5 LAWS OF MOTION In this video you will learn about the concept of Rolling friction and what is the reason of using wheel and ball bearing in machineries . Next we have discussed about motion of a car in a circular track on flat road and banked road . Here we have derived the maximum velocity of a car in a circular turn on the road.
