Writing about friction
Scrubbing helps clean, but scrubbing too hard can damage an object.
Fluid friction is used a lot in water parks so we can slide smoothly and fast down giant slides. A ball rolling on a surface Fluid Friction[ edit ] Here on Earth we tend to take air resistance aka.
It allows you to clean your teeth. In general, more viscous fluids are thicker, so honey has more fluid friction than water. Another way to reduce friction is to change the types of materials in contact with one another. Likewise, you could not stop without the friction of the brakes and the tires.
Describe the various types of friction.
Examples of friction
The harder the surfaces are pushed together such as if another box is placed on the crate , the more force is needed to move them. This is why we rub our hands together when it's cold. Our sneakers will sound like cars when they burn rubber. It is also called drag. Rolling Friction - Rolling friction occurs when a round surface rolls over a surface, like a ball or wheel. Uses of Friction by Ron Kurtus revised 18 July Although you normally hear about trying to reduce or eliminate friction, it actually has some important uses. Quite often uses of friction can be seen from how things would be without friction. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Example: Static friction prevents an object like a book from falling of the desk, even if the desk is slightly tilted. Since friction is a resistance force that slows down or prevents motion, it is necessary in many applications where you might want to hold items or do things and prevent slipping or sliding.
Fun facts about Friction Although wheels are great for rolling and reducing friction, they couldn't work without friction.
