Friction advantages:
Sliding Friction: People need to have the reaction.
For example: shoes friction with the ground, the people forward,
Rolling friction; reduce friction and wear when the role.
For example: • Boules ancient carrying heavy loads, the use,
Static friction: fixed object, and prevent the other objects in the impact of the campaign
For example: chopsticks夹起food;
Friction disadvantages:
Sliding Friction: Wear causing objects
For example: tires, parts wear;
Chalk's wear;
Rolling friction; not produce large enough reaction force
For example: it is very difficult to wear溜冰鞋when a drag objects;
Static friction: increasing the resistance movement
For example: rusty wheels, unable to rotate.

Advantage of frictional force:
Sliding friction: Can produce the reacting force that people need .
For example: The shoes and ground rub, make people advance ,
Rolling friction; Wearing and tearing function produced while reducing the friction.
For example: Ancient to get away the use of the wood at carrying heavy objecting,
Static friction: Regular object, the movement of preventing objects and emerging when affected by other strength
For example: The chopsticks are inserted the food;
Harm of frictional force:
Sliding friction: Cause the wearing and tearing of the object
For example: The tire, the wearing and tearing of the spare part;
Wearing and tearing of the chalk;
Rolling friction; Can't produce enough great reacting force
For example: It is very difficult to pull an object while wearing the skating shoe;
Stiction: Obstruction while increasing the movement
For example: The wheel getting rusty is unable to rotate.

Friction force advantage:
Sliding friction: May have the reacting force which the people need.
For example: The shoe and the surface friction, enable the human to go forward, rolling friction; Reduces when the friction produces abrasive action.
For example: Ancient times transported when the heavy item rolling logs use, static friction: The movement which the fixed object, prevents the object when to receive its aid from others influence produces for example: The chopsticks clamp food;
Friction force fault:
Sliding friction: Creates the object the attrition for example: Tire, spare part attrition;
Chalk's attrition;
Rolling friction; Cannot have the foot 夠 big reacting force for example: Puts on the ice skate time is very difficult to drive an object;
Static friction force: Increases when the movement resistance for example: The rusty wheel is unable to rotate.
