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
Lubrication, is one way.Two ways to reduce friction are :.Lose weight.Wet the surface
Friction can be increased by reducing the speed of the moving object. Friction can also be increased by increasing the weight of the moving object.
With increased surface areas in contact, friction increases.
friction \
Rougher surface and more weight to the object increases friction
Rubbing two things together. Even if you're just sliding across a carpet, that's friction too.
1. Increase the normal reaction acting on the objects by pressing them together. 2. Increase the coarse nature of the surfaces so that the coefficient of friction is also increased.
