Making surfaces smooth and hard
Rolling instead of sliding (roller bearings instead of sleeve bearings)
Lubrication
smooth surfaces rollerblades cooking spray in pans
You can stand on bare ground tile or any other conductors (water, aluminum, etc.)
Use lubricants or powders specifically designed to reduce friction between the shoe and the foot. Choose shoes with a smooth, seamless inner lining to minimize rubbing against the skin. Consider wearing moisture-wicking socks to reduce friction caused by sweat and moisture buildup.
Decreasing friction:- add a lubricant (like oil in a door hinge)- rolling objects (e.g. rollerblades)- streamlining (like making an aircraft a special shape to reduce wind resistance)Source(s):I have a good memory and listen in school

Decreasing the mass or Decreasing the velocity
Important factors in decreasing Kinetic Energy are Gravity and 'drag' from Friction.
There are different ways through which helpful friction be increased. The easiest way is using coarser or rougher surface to increase resistance.
applying a brake
Decreasing the block in contact with the table reduces the normal force acting on the block, which in turn decreases the frictional force. This results in a lower kinetic friction force between the block and the table.
when i am ask is friction important i say the answer is yes. friction is important and can help people in many different ways. like cars for a example cars use friction to drive on the road. there is many different types of friction to; dry friction, fluid friction, lubricated friction, skin friction, internal friction, ect..... all of these types of frictions can be different a different way.
Activities that require increasing friction can include using sandpaper to roughen a surface or tightening the grip of shoes with a shoelace. Activities that involve decreasing friction can include applying lubricant to machine parts or gliding on ice skates with a thin layer of water on the ice.
