Learn about the seven most common types of friction forces and their applications in our daily lives. Discover methods to reduce friction too.
Friction is a force that resists motion between two surfaces in contact with each other. It is a vital force in our daily lives, as it enables us to walk, drive, and even hold objects. There are several types of friction forces, each with its unique characteristics and applications. In this article, we will discuss the seven most common types of friction forces.
1. Static Friction
Static friction is the force that keeps an object at rest when a force is applied to move it. This force is present when the applied force is not enough to overcome the friction between two surfaces. It is a necessary force to enable us to walk and keep objects stationary.
2. Kinetic Friction
Kinetic friction is the force that resists the motion of an object when it is in motion. This force is present when two surfaces are in contact and rubbing against each other. It is also known as sliding friction, and its amount depends on the nature of the surfaces in contact.
3. Rolling Friction
Rolling friction is the force that resists the motion of an object when it rolls over a surface. This force is present when a wheel or a ball rolls over a surface, and its amount depends on the nature of the surface and the shape of the object.
4. Fluid Friction
Fluid friction is the force that resists the motion of an object through a fluid, such as air or water. This force is present when an object moves through a fluid and is proportional to the object’s speed and size.
5. Lubricated Friction
Lubricated friction is the force that resists the motion of an object when a lubricant is applied
