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 schoolUse 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 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.
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.
Decreasing friction can be useful in situations like lubricating bike chains, reducing wear and tear on moving parts, and making objects easier to slide or move. Increasing friction can be beneficial for improving the grip of tires on the road, preventing slipping on floors, and enhancing the effectiveness of brakes.
Friction is a force which always acts opposite to the force applied on the surface of a body. This opposing force is necessary for many day-to-day activities. Had friction not been there, you wouldn't have been able to walk, write, drive, etc.There are various ways of increasing or decreasing friction. Lubrication, use of ball bearings, use of anti-friction alloys, use of compressed air, etc are some of the ways of decreasing friction.While roughening the surface, drying the surface etc are the ways of increasing friction.Friction occurs because the surface of any object is rough.No surface is completely smooth, they are rough (if not visibly, then microscopically). When they touch each other, the ridges catch on each other, producing heat/friction.because when 2 objects rub together it makes a force that interacts with the other object.

You can stand on bare ground tile or any other conductors (water, aluminum, etc.)
Making surfaces smooth and hard Rolling instead of sliding (roller bearings instead of sleeve bearings) Lubrication
Decreasing the mass or Decreasing the velocity
Important factors in decreasing Kinetic Energy are Gravity and 'drag' from Friction.
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.

Okay 2 ways for the friction to increase is speed and non lubricant
Friction increases or decreases based on the surface changes. If a box were sliding down a smooth hill that suddenly becomes quite rough, then friction would increase. It would be the same vice versa for decreasing friction.
1) using a lubricant film between moving parts. 2) using low friction materials, such as Teflon.3) reducing surface roughness.
