What term describes the resistance to an object sliding across a surface?

• A. Gliding
• B. Guiding
• C. Friction
• D. Matching

Answer: (C)

Friction is the resistance to motion between two surfaces in contact. It can be static, which resists starting movement, or kinetic, which acts when sliding occurs and is typically smaller than static friction. In skiing, the friction between the ski base and the snow controls how quickly you slow down, stop, or when you begin to slide during a turn. Other terms don’t describe this resistive force: gliding refers to movement itself, guiding is about steering, and matching isn’t a term used for resistance between surfaces.
