Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: 1. **Static Friction**: This type of friction occurs when two surfaces are at rest relative to each other. 2. **Kinetic Friction**: Kinetic friction arises between two objects that are sliding against each other. 3. **Rolling Friction**: This occurs when a round object rolls over a surface, like a ball rolling on the ground. 4. **Fluid Friction**: Fluid friction, also known as viscous drag, occurs between layers of fluid that are moving relative to each other, like air resistance or water resistance.
