Well friction is a force that acts between two surfaces in contact. Although it has unwanted effects like loss of energy or wear and tear, yet it is a very important force and is thus sometimes called 'the necessary evil'. At homes friction needs to be increased on stairs, floors, especially bathroom floors in order to prevent accidents due slipping or skidding. The greater friction between shoes/feet and the floor, the lesser is the chance of slipping. In bathrooms, water/soap on the floor may reduce friction drastically thus greatly increasing the chances of slipping.
it increased the food productions for the war needs.
Friction does not speed up an object; it creates drag and slows it down.
In general rolling friction is any friction specifically related to the rolling motion. The friction on the axle to hub bearing, the tire flexing, the tire tread on the surface of the road and so on.
Friction is independent of speed once an object is moving since faster does not mean more friction.
Friction is the force produced when two objects are rubbed. Rough surfaces exhibit more friction while smoother surfaces tend to be almost frictionless.
With increased surface areas in contact, friction increases.
The friction will also double as Friction= (friction coefficient)(normal reaction)
There are different ways through which helpful friction be increased. The easiest way is using coarser or rougher surface to increase resistance.
Friction can be increased in a given situation by increasing the roughness of the surfaces in contact, increasing the force pressing the surfaces together, or by using materials with higher coefficients of friction.
Speed it up!
Friction can be increased by increasing the roughness of the surfaces in contact, increasing the force pressing the surfaces together, or using materials with higher coefficients of friction. Additionally, increasing the surface area in contact can also increase friction.
Tires, grips, pedals and brakes needs to have high friction, while all rotating parts needs to have low friction.
Fluid friction.
movement and heat
by runnig or go with more speed
Okay 2 ways for the friction to increase is speed and non lubricant
An example of friction reducing the efficiency of a machine is when two moving parts rub against each other, causing heat and wear. This can lead to energy loss and increased maintenance needs, decreasing the overall efficiency of the machine.
