Here are two advantages and one disadvantage of friction:

• Advantages: Friction allows us to walk without slipping by providing grip between our shoes and the ground. It also enables brakes in vehicles to work, converting kinetic energy into heat to slow down or stop motion.
• Disadvantage: Friction causes wear and tear on moving parts of machinery, leading to damage and requiring more energy to overcome the resistance.
