Answer 1

Three ways of reducing friction are

• Polishing the rough surface.
• Oiling or lubricating with graphite or grease the moving parts of a machine.
• Providing all bearings or wheels between the moving parts of a machine or vehicle reduce friction and allow smooth movement as rolling friction is less than sliding friction.
