Ways To Reduce Friction

Friction is a force that resists motion when two surfaces touch. While friction is helpful in many cases—like keeping you from slipping—it can also slow things down or cause materials to wear out over time. In machines or moving parts, too much friction leads to energy l...

Try pushing a heavy box across a rough concrete floor. It feels hard to move, right? That’s because of the friction between the two surfaces in contact.

Now, imagine placing the same box on a smooth surface. It slides more easily.

Rough surfaces have tiny bumps that lock together. When we polish or smooth a surface, those bumps becom...
