🔍 Key Concepts

• How metal looks when it is moving smoothly against another surface with plenty of lubricant • Difference between a surface that grips (friction) and a surface that lets parts slide easily • What wear patterns might look like if there is not enough lubrication

💭 Think About

• Which choice describes a surface that would REDUCE friction and allow parts to slide easily for a long time? • Which descriptions sound like the surface has been roughened or damaged, instead of protected by oil or grease? • Think about machine shafts and bearings you’ve seen—how does the metal look where it runs in good oil all the time?

✅ Before You Answer

• Eliminate any answer that suggests a rough or textured surface that would increase friction • Ask if the word used suggests damage or wear rather than healthy lubrication • Pick the description that best matches a smooth, low-friction contact area
