Smoothing of a surface to remove physical snags, (Varnish or sanding for wood) and applying a lubricant (usually oil) are the two primary ways to reduce friction between two surfaces. If surface modification is not possible, applying a lifting force to take some of the weight off the ground reduces friction force by reducing the normal force of the floor on the object. (Though this doesn't influence the friction properties directly, it just reduces the effective weight of the object when calculating friction.

What two ways can you change friction?
You can increase friction by increasing the roughness of a surface or by increasing the force pushing the surfaces together. You can decrease friction by using lubricants or reducing the contact area between the surfaces.
How is friction a force?
Due to friction velocity of a body gets reduced, reduction in velocity causes change in velocity. This change in velocity leads to production of acceleration.(Because only acceleration can produce change in velocity either its direction or its magnitiude). And only a force can cause the acceleration hence friction is a force.

If friction isn't dependent on surface area but only on the coefficient of friction between two surfaces and the reaction force then why do racing cars use bigger tires with greater area?
Friction doesnt not depend on the surface area...but the force of friction does! We cannot change the friction of a material but we can change the force due to that friction on another material in contact with it. Using this concept, racing cars have bigger tires to minimise the force of friction acting on them. They cannot change the friction of the road, so they change the resultant force on the tires.
Is friction the rate of change in velocity?
Acceleration is the rate of change in velocity. It has nothing to do with friction, unless friction is causing the change.
Name two ways in which friction can be increased?
Okay 2 ways for the friction to increase is speed and non lubricant

How many ways can you make change for a dollar using only dimes and nickels?
22 ways
In what ways can friction be helpful?
Friction is necessary for wheels to rotate and nails to keep in walls.
What are the helpful ways of friction?
Without friction, we couldn't walk or grip onto anything.
What are ways friction can be increased?
Speed it up!
What are substances that change sliding friction to fluid friction?
The materials that, in general, change sliding friction to fluid friction are called lubricants. This class of materials includes oil, grease and the like.
