Friction: Types and Characteristics

No. Date Physic "Firtion" Aface acting onthe pant of Contact of the Called Friction object which opposes the relative Motion IS Friction is of three types 8 1.) Static Friction When one body tend 18 Move over the Survace It is opposing Force which Come into play Place. of the other body but acheal Motion is not taking 2) Cirling Friction : It Is maximum Value of static Friction when body IS at Verge of starting Michon . limiting Friction= ficmax H5R.
