assuming that you're asking a multiple choice question, waxing skis reduces friction so that you can move faster on the snow. grease and oil are used as lubricants. they reduce friction in most instances. throwing sand on an icy driveway would increase friction between a cars tires and the ice. a good rule of thumb is that most liquids work as lubricants, most gritty or solid stuff works to increase friction, and powder can do either.

i dont

well immediatly when i hear the word friction i think of tires and u need to add something to make it intentionally go faster so an example would be " adding grease to gears on a bike." Heather - 14 - MI ^^^ this is decreasing friction. Adding friction would be like throwing sand on a icy driveway so you don't slide..
Yes it is because it states that in Easton's 12th law of facts!
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.
by increasing smothness wecan decrease the friction and vice versa

reduce the area of contact, real life example ball bearings on the floor instead of block of wood
TO REDUCE FRICTION: We can use fine powder on the carrom board to reduce friction
oiling a squeaky door
You walk and that is the example of friction
