Beau- Friction is used in car brakes to slow down or stop the vehicle by converting kinetic energy into heat.
- Friction is used in the grip of shoes to prevent slipping and provide traction when walking.
- Friction is used in the striking of a match to generate heat and ignite the match head.

What household object use friction?
A broom sweeping a floor uses friction to push dirt and debris along the ground.
What is the example effect of desirable friction?
Very simply, desirable friction can be found on cars. Brakes are a good example. Another one is when you rub your hands together to produce heat. Striking a match is another and also uses a chemical reaction to produce a flame. All friction produces heat and many hundreds of uses have been found to utilise this heat.
What are the 3 types of friction and its definition?
The 3 types of friction are static friction (force between stationary objects), kinetic friction (force between moving objects), and rolling friction (force between a rolling object and a surface). Friction is the resistance that one surface or object encounters when moving over another.
Misuse and uses of friction?
Misuse of friction: Excessive friction can cause overheating and wear on moving parts, leading to equipment failure. Too little friction can also be dangerous, as in the case of slip hazards. Uses of friction: Friction is essential for everyday activities like walking, driving, and gripping objects. It is also used in machinery, brakes, and clutches to control and transfer motion.
Is it true that every machine uses some of its work input to overcome friction?
Yes, it is true that almost every machine uses some of its work input to overcome friction. Friction is a force that opposes motion and can cause energy losses in a system, which often results in the need for extra work input to maintain operation. Reducing friction through lubrication or design improvements can help optimize machine efficiency.
