Friction is a force that makes things slide less easily. When we reduce friction, things move better and use less energy. Here are some simple ways to reduce friction:
Use Lubricants: Adding oils or greases can help surfaces slide against each other more easily. For example, machines in factories can cut friction by 50% to 80% when they are well-lubricated.
Make Surfaces Smooth: The smoother a surface is, the less friction it creates. Studies show that a shiny, polished surface can lower friction by up to 90% compared to a rough surface.
Choose the Right Materials: Some materials don't create much friction, like Teflon and certain types of ceramics. For instance, Teflon has a very low friction level of just 0.04.
Shape Matters: Designing things to be more aerodynamic helps them move through air without getting slowed down. For example, cars that are shaped to be sleek can cut air resistance by up to 30%, which helps them use less fuel.
Ball Bearings: Using ball bearings helps things roll instead of slide. Rolling creates much less friction—up to 10 to 100 times less—than sliding does.
By using these methods, we can make machines and vehicles work better, in line with Newton's laws of motion.
