Why friction is useful

Skip to content Home Research Paper How friction is useful to us? Research Paper. Ben Davis February 9, How friction is useful to us? How does friction help us write? How can you walk without friction? Is friction useful to ships? 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.

World View. The force of friction will depend on the material of the rubbing surface. It also depends on the speed or intensity at which two surfaces come into contact with each other.

To overcome friction, you need to work more and put extra effort. In contrast, force is any interaction that tends to change the motion of the object. Without friction between the shoes and the ground, you cannot walk properly. If there is no friction, all of us would be sliding around without any control over ourselves. Friction holds your shoe to the ground so you can walk around.

Since only a little amount of friction is present on ice, it is often a bit hard to walk on the slippery surface of the ice. While driving vehicles and riding bicycles, friction occurs between the wheels of the vehicle and the surface over which the vehicle is traversing. If the friction is zero, the vehicle would fail to move forward. It is only because of friction that we are able to stop our vehicle. All of us write using either a pen or a pencil in our daily life. What happens when you hold your pen or pencil?

Have you ever tried giving a thought about it? In case you are wondering, the answer to your question lies in the phenomenon of friction. 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.
