Friction produces _________

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 arises when there is an attempt to slide one surface over another. 2. **Relative Motion**: When we say "relative motion," we refer to the movement of one surface in relation to another. For example, if you slide your hand across a table, your hand is moving relative to the table. 3. **Effect of Friction**: When two surfaces experience relative motion, friction acts between them. This interaction leads to certain effects, one of which is the generation of heat. ...
