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.
You can stand on bare ground tile or any other conductors (water, aluminum, etc.)
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
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.
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.
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.
