Friction increases or decreases based on the surface changes. If a box were sliding down a smooth hill that suddenly becomes quite rough, then friction would increase. It would be the same vice versa for decreasing friction.
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.
movement and heat
by runnig or go with more speed
Okay 2 ways for the friction to increase is speed and non lubricant
More friction acts on a diver when they dive because of the increased density of the water.
Some common questions about friction that are frequently asked include: What is friction and how does it work? What factors affect the amount of friction between two surfaces? How can friction be reduced or increased? What are the different types of friction?
As the coefficient of friction is not function of the area or not related to the area of the contact surface so the coefficient of friction remains constant on the increase of the contact area. The coefficient of friction depends upon the material of the friction surfaces only.
