give the different types of friction and explain each with example
Answers
Answer:
sliding friction, rolling friction and static friction. hope this will help you ..
Answer:
There are three primary forms of friction. The first two are very similar and depend on the state of the object in question.
1) Static Friction:- This state of friction is applied between two objects when they have been in contact for a long time and have no relative motion between them. Static friction is applied due to cold welding between the two surfaces of contact.
2) Sliding Friction(Kinetic Friction):- This state of friction is applied between two objects when they have relative motion between them. Kinetic friction's magnitude is always less than or equal to that of the magnitude of the maximum static friction. Kinetic friction is always applied to reduce the relative motion, or it is applied opposite to the direction of relative motion.
3) Rolling Friction:- This state of friction is applied between two objects when at least one of the objects undergo rolling motion. Rolling friction is always applied in the opposite direction of the relative motion. So in this case too the friction is applied in the opposite direction to the rotation. Thus the friction is applied in the same direction as the motion of the rolling object. (Only in real scenario there is a depression in the object thus there is a friction applied in the opposite direction to the direction of motion.)
