Today we are going to learn five fascinating facts about friction. Fact number one friction is caused when two objects rub up against each other friction works against emotion and acts in the opposite direction. The amount of friction depends on the materials from which to two surfaces are made the rougher the surface the more friction is produced. Rolled a bowling ball on a surface with travel further on a wooden floor than it would on a carpeted floor. This is because there is more friction between the carpet and the ball fact number two.
Three types of friction are dry fluid and rolling friction dry friction is the most commonly known friction and occurs when two storms objects touch each other and can be categorized into two parts. If the objects are not moving. It is called static friction. If they are moving it is cold kinetic friction the next it’s fluid friction, which involves a fluid like water or air resistance. The last is rolling friction, which occurs when a round surface rolls over another surface such as a ball all wheel. act number three action can also occur between layers of a liquid when friction occurs between layers of a liquid.
It is known as viscosity the more viscosity and liquid has the thicker the liquid is Honey, and oil are more viscous than water viscosity measures the resistance of a liquid to flow liquid can create less friction. For example, it’s harder for your bicycle to stop on a wet path than a dry one because the water creates a barrier between the bicycle wheels and the path. fact number four friction can be reduced by using a lubricant when machines start to break down or aren’t working. Well friction between moving parts may be too strong oil.
It’s often used to get these moving Parts working again, and it decreases the friction fact number five. There’s friction between our feet and ground that we stand on which keeps us standing up. Have you ever tried to walk on Ice you’ll find it is much harder to walk on a slippery surface and you will likely Fall. This is because there is less friction between your food and the ice then there is with your foot and the hard ground. I hope you enjoy my five fascinating facts about friction. See you next time.
