Friction is a force that opposes motion between two surfaces that are in contact with each other. It is important because it affects the movement of objects and can either help or hinder certain processes.
Friction plays a major role in everyday life and technology. It allows us to grip objects, walk, and drive vehicles. At the same time, it can also cause wear and tear on machines and slow down processes.
No, friction cannot be eliminated completely. It is a natural force that occurs whenever two surfaces are in contact with each other. However, it can be reduced through the use of lubricants or by using smoother surfaces.
The force overcoming friction can be measured using a device called a force gauge. This device measures the amount of force required to move an object against a surface with friction present.
There are a few ways to increase the force overcoming friction. One way is to increase the weight of the object. Another way is to increase the surface area of the object in contact with the surface. Additionally, using rougher materials can also increase the force overcoming friction.
