Lubricants are substances that reduce friction between surfaces in motion. They can be found in various forms, such as oils, greases, and gels. By creating a slippery layer, lubricants help machinery, engines, and even everyday items like door hinges work smoothly and efficiently. This not only prevents wear and tear but also extends the lifespan of equipment. In addition to mechanical uses, lubricants are also important in personal care products, such as personal lubricants used during intimate activities. These products enhance comfort and reduce friction, making experiences more enjoyable. Overall, lubricants play a vital role in both industrial and personal applications.
