Friction Questions and Answers Latest Update | 2024/2025 | 100% Pass Friction happens when: The irregularities of two surfaces interact with each other. What factors influence the amount of friction? The force pressing the surfaces together and the roughness of the surfaces. Do rougher surfaces usually have more or less friction? More friction. Is there generally more or less friction between a heavy object and its surface compared to a light object and its surface? More friction. What type of friction exists between two surfaces that are not moving? Static friction. 2 What type of friction occurs between moving surfaces? Kinetic friction. Which type of friction is stronger than sliding friction? Static friction. Rank the types of friction from greatest to least: static, kinetic sliding, and kinetic rolling. 1. Static friction 2. Kinetic sliding friction 3. Kinetic rolling friction Liquids that minimize friction are called: Lubricants. How is friction beneficial in tires and brakes? It makes stopping and moving easier. How will increasing the force pressing surfaces together affect the amount of friction?
