Does friction depend on mass?

Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Understanding Friction**: Friction is a force that opposes the relative motion between two surfaces in contact. It plays a crucial role in everyday activities, such as walking, driving, and holding objects. 2. **Factors Affecting Friction**: The frictional force depends on two main factors: - The **normal force** (the perpendicular force exerted by a surface on an object resting on it). - The **roughness of the surfaces** in contact (how smooth or rough the surfaces are). ...
