STEPS TO REDUCE FRICTION IN OUR DAILY LIFE:

1. Polishing: When we polish a surface, its roughness [unevenness] decreases. The surface smooth and friction gets reduced.
2. Lubrication: We could use lubricants [like grease, oil, etc.] in machines, the work smoothly and reduce friction.
3. Ball Bearings: We know that rolling friction is slightly less than sliding friction. We can use ball bearings.
