Some random tired thoughts...
roughen a surface
add lubricants
lighten the sliding object.
use wheels
start the object moving, then measure the friction

Think about sex- to decrease friction, add lube. To increase friction, be dry. In cars, you need oil, or your parts dry up and rub together. Typically, the more viscous the lubricant used to decrease friction, the longer it will last.

Decrease: lubrication springs to mind.
To increase, you can add a layer of soft material that will absorb energy, make materail rough, or you can apply pressure (since friction is proportional to the pressure)

Increasing friction= rubbing creates heat. For example an eraser on your hand, you'll start to feel a burn
Decreasing friction= Stop rubbing! lol. That's a good question though. I like it.

to improve friction between 2 surfaces you may ought to make each floor tough. in case you opt to cut back friction you may comfortable the two surfaces. many the thank you to try this. get innovative.
