Friction is a force that opposes relative motion between systems in contact. One of the simpler characteristics of friction is that it is parallel to the contact surface between systems and always in a direction that opposes motion or attempted motion of the systems relative to each other.

Roughness/smoothness of the sliding objectRoughness/smoothness of the surfaceshape or design of the objectNormal forceacting upon the sliding bodiesSmooth surfaces slide over surfaces easily compared to rough ones. One can notice the irregularities at the microscopic scale. These irregularities hinder the sliding between the surfaces. Thus, the roughness higher is the more friction. A snow-covered surface offers very little friction. Cyclists use tires with high irregularity (grip) to increase...
It is impossible to have perfectly smooth surfaces. Each surface will have its own roughness. This roughness, combined with the roughness of the sliding object, will give rise to friction. Other factors affecting friction include the force pushing the surfaces together, the type of materialsinvolved, the temperature of the surfaces, and the presenc...
The force in the normal direction (perpendicular to the sliding plane) will increase the interaction between the surface thus increasing the friction. Friction is thus directly proportional to the normal force applied. [f = μ * N, where μ is the coefficient of friction] The force observed in the normal direction is generally the weight of an object...
Friction exists not only in solid surfaces but also in liquids and gases. However, compared to sliding against a solid surface like a road, air or waterprovides very little friction. When we deal with fluid friction, the design of the object becomes crucial, and factors affecting friction must be considered. Generally, a streamlined design is chose...
Friction is directly proportional to the normal force but is independent of the area of contact. [f = μ * N, where μis the coefficient of friction]
Rolling friction is always less than sliding friction. The introduction of wheels is also a factor that can reduce friction drastically. Try sliding your suitcase compared to a stroller bag, you can feel the ease of movement due to the drastic reductionin friction. For example: roller skates reduce friction and hence allow us to move faster compare...
Fluid friction is always generally less than dry friction. Fluid friction is the friction between an object and a fluid (liquid or gas). For example, lubrication works on the principle of fluid friction. During lubrication, a viscous fluid acts as a layer between two sliding surfaces and reduces the friction between them.

Friction is a contact force. It acts against the movement of an object. There are many examples of where friction is a useful force. For example, friction is why we do not slip when we walk...
Feb 17, 2023 · Friction or frictional force is defined as the force that resists an object’s motion on a surface. The object can either be stationary or in motion relative to the surface. Friction occurs where the object is in contact with the surface.
Friction arises in part because of the roughness of the surfaces in contact, as seen in the expanded view. For the object to move, it must rise to where the peaks of the top surface can skip along the bottom surface. Thus, a force is required just to set the object in motion.
Friction is a force that resists the movement of objects past each other. Friction always works in the opposite direction to the direction the object is moving.

Influenced by Fluid Properties: The density and viscosity of the fluid play a significant role in the magnitude of drag experienced by an object. Shape Factor: The shape of the object significantly affects drag. Streamlined shapes are designed to reduce drag, enhancing efficiency in vehicles and aircraft.
