Introduction:
Friction is an opposing force that comes into play when two surfaces come into contact with each other. It is a force that resists motion and can be either beneficial or detrimental depending on the situation. In many cases, friction is a necessary evil that needs to be overcome in order to accomplish certain tasks. However, in some situations, the goal is to minimize friction to achieve maximum efficiency. In this article, we will explore the different types of friction and find out which one is the minimum.
Types of friction:
Static friction:
Static friction is the type of friction that occurs when two objects are at rest and are not moving in relation to each other. It is the force that needs to be overcome to set an object in motion.
Kinetic friction:
Kinetic friction is the type of friction that occurs when two objects are in motion relative to each other. It is the force that resists the motion of the object.
Rolling friction:
Rolling friction is the type of friction that occurs when an object rolls over a surface. It is generally lower than static and kinetic friction because the area of contact is much smaller.
Fluid friction:
Fluid friction is the type of friction that occurs when an object moves through a fluid. It is also known as drag. Fluid friction can be further divided into two types, namely laminar and turbulent friction.
Laminar friction occurs when the fluid flows in a smooth and orderly manner, while turbulent friction occurs when the fluid flows in a chaotic and irregular manner. In general, turbulent friction is higher than laminar friction.
Which friction is the minimum?
Fluid friction is the type of friction that is minimum. This is because fluid friction is directly proportional to the viscosity of the fluid and the speed of the object. Therefore, by reducing the viscosity of the fluid and using streamlined shapes, the amount of fluid friction can be minimized.

Conclusion:
In conclusion, friction is a necessary evil that needs to be overcome in many situations. However, in some cases, it is necessary to minimize friction to achieve maximum efficiency. Fluid friction is the type of friction that is minimum, and it can be reduced by using streamlined shapes and reducing the viscosity of the fluid. By minimizing friction, we can increase the efficiency of the system, reduce wear and tear, and save energy.
