Friction

Friction is a force that resists motion between objects in contact. It acts in the opposite direction of movement and can transform kinetic energy into heat. Friction is categorized into sliding, rolling, and fluid types, each with unique characteristics and examples. Sliding friction occurs when surfaces slide over each other, rolling friction involves objects like wheels, and fluid friction occurs in liquids and gases. Understanding friction is crucial for calculating forces affecting objects.
