oil, graphite, grease
The four ways to decrease friction are: lubrication (using substances like oil or grease to reduce friction), using smoother surfaces, reducing the weight pressing the surfaces together, and using ball bearings or rollers to replace sliding friction with rolling friction.

Decrease friction .
Three ways to decrease the force of friction are- 1.)Polishing 2.)Lubrication 3.)Ball Bearings
by using a lubricant to decrease the friction.
Use lubricants such as oil or grease to reduce friction between surfaces. Use smooth or polished surfaces to minimize roughness and friction. Ensure proper alignment and regular maintenance of moving parts to avoid unnecessary friction. Reduce the weight or force pressing the surfaces together to decrease friction.
You can increase friction by increasing the roughness of a surface or by increasing the force pushing the surfaces together. You can decrease friction by using lubricants or reducing the contact area between the surfaces.
1) using a lubricant film between moving parts. 2) using low friction materials, such as Teflon.3) reducing surface roughness.
Polish the interacting surfaces or decrease the normal force acting on the moving object.
Apply a larger force. Make the object less massive. Decrease air resistance acting on the object. Decrease the coefficients of friction by using a 'smooth' surface, where friction is negligible.
Friction is decreased by means of lubrication.
