Final answer:
One way to reduce friction between two surfaces is to apply a lubricant, such as oil or grease.
Step-by-step explanation:
One way to reduce friction between two surfaces is to apply a lubricant. A lubricant is a substance that is applied between two surfaces in contact to reduce friction and allow smoother movement. For example, you can use oil or grease to lubricate the gears of a machine, which makes them rotate more smoothly with less friction. The lubricant forms a thin layer between the surfaces, reducing the direct contact and reducing friction.
