Since friction is a force that works against motion, the friction between your shoes and the concrete works against the motion of you slipping and falling.
Friction is also necessary to perform many simple tasks in our daily lives. Take writing for example. When you hold your pen or your pencil, it is the friction between your finger tips and the pen that keeps the pen from sliding out of your hand. Think of trying to sand a block of wood or cutting a block of wood in half with a saw: friction is at work in both cases. Even though friction is popularly viewed as a force that increases the gas consumption of vehicles or one that causes heat to be generated between moving parts, it makes the world a much safer place to live in and most certainly helps us increase our productivity.

How does friction help us write? How can you walk without friction? Is friction useful to ships? What is friction produce? You light a match using friction. As you strike a match, friction creates enough heat to ignite a chemical compound in the match head that then burns the rest of the match head.
Car brakes work because of friction. Shoes designed for some sports have special soles to use friction to your advantage. Football boots have studs to increase friction by sticking to cracks in the ground. A violinist puts rosin on his bow to increase friction between the bow and the violin strings, therefore producing sound. However, friction can also be a real nuisance. If a door hinge squeaks, the noise is caused by friction. Cooked foods tend to stick to pans. Teflon on non-stick cookware reduces friction between the food and the pan, causing the food to slide.
Competitive swimmers wear specially designed racing suits to reduce the friction between themselves and the water so that they can swim faster. Silicone aerosols, oils, grease and ball bearings are all used to reduce friction.
Air resistance force is the force of air pushing against a moving object. Air resistance also called drag is a type of frictional force. Like all frictional forces, the force of air resistance always opposes the motion of an object. Usually, the air resistance force is not very strong.
When you walk, for example, you are affected by air resistance force, but it does not really slow you down. If you start running, the air resistance force will become more noticeable. Rosin - a hard resin ranging in colour from amber to dark brown. Used for varnishes and other products, to increase friction, e. Static electricity - a stationary electric charge that builds up on an insulated object such as a thunder cloud Streamlined - to design or build something with a smooth shape so that it moves with minimum resistance through air or water Surface area - a solid flat area.
Need help? How to videos Why join? Friction and resistance. What are friction and resistance? Although wheels are great for rolling and reducing friction, they couldn't work without friction. It would be really tough just to stand up without friction. Friction can generate static electricity. The harder two surfaces are pressed together, the more force it takes to overcome the friction and get them to slide. Fluid friction is used a lot in water parks so we can slide smoothly and fast down giant slides.
Racing cyclists crouch down low on their bikes to reduce the air resistance on them. This helps them to cycle faster. They also wear streamlined helmets. These have special, smooth shapes that allow the air to flow over the cyclist more easily. Ice causes very little friction , which is why it is easy to slip over on an icy day. However this is a good thing for ice skating and sledging.
When you rub your hands together quickly the friction warms them up.
