Question and answer
how can friction be reduced?
Friction can be increased by using a rougher, or coarser, material. Sand paper is one example. Friction can be reduced by using a smoother material, this can be silk, or very very finely milled metal. [ Additionally, lubricants like oil can be used, the oil gets between where two materials make contact and effectively fills in the gaps to make rough surfaces become smoother, and allow them to
slide past each other more easily. ]

Weegy: a1) In a car engine, the parts rub against each other - pistons rub in the cylinders, the crankshaft rubs against its bearings, etc, etc. Sme thing in the transmission. [ The friction between those parts means that you have to apply some force to get the engine and transmission to turn. That means that some of the power of the engine is used to overcome friction instead of actually moving the car - so you use more fuel, which costs you ... (More)
