Summary: One way to reduce friction is by using oil or grease. This is called lubrication. When you oil the chain of your bike, the surfaces move past each other more easily. Snowboarders wax their boards to reduce the friction between their board and the snow. Tags: science student-book-7 physics Created: 2026-05-21 Last Updated: 2026-05-21
