Friction can be maximized or minimized in several ways depending on the material, device construction and purpose, for example:Minimizing friction of a circling axis can be made by bearings, which usually have rolling balls. Rolling has usually less friction than sliding.In slide systems, friction can be minimized in various ways such as:Polishing the surface of both sliding sides (the opposite will increase friction)Adding a liquid such as oil between them. Oil fills the micro gaps on the surfaces therefore creating a slippery surfaceUsing certain techniques, e.g. air insulation, magnetic insulation
Three ways to decrease the force of friction are- 1.)Polishing 2.)Lubrication 3.)Ball Bearings
friction is what makes it hard to rub two pieces of sand paper together
The force of friction between two objects is the product of the normal force and the coefficient of friction. The normal force is the component of force that is perpendicular to the plane of friction. For example, if you are pushing on a block of wood on the floor with a force F at an angle of 30 degrees above the horizontal, then the normal force N = F sin 30. The coefficient of friction is specific to the two materials, in this example the block of wood and the floor. In addition, there is a static coefficient of friction (applicable to a stationary situation) and a kinetic coefficient of friction (applicable when the object is already moving).
Okay 2 ways for the friction to increase is speed and non lubricant
Speed it up!
by runnig or go with more speed
There are different ways through which helpful friction be increased. The easiest way is using coarser or rougher surface to increase resistance.
Going faster and run fast
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.
With increased surface areas in contact, friction increases.
Rougher surface and more weight to the object increases friction
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?
1. By friction. 2. by magnetism
Use a surface that has a higher coefficient of static/kinetic friction and/or add more force downwards on the object.
Friction is harmful on a bike by causing wear and tear on the components like brake pads and tires, leading to replacements. It can also make pedaling more difficult, resulting in increased fatigue for the rider. Friction is helpful on a bike by providing the necessary grip between the tires and the road for stability and control. It also aids in slowing down the bike when brakes are applied.
