Here's why:
* Friction opposes motion: Friction is a force that resists the relative motion between two surfaces in contact. It always acts in the opposite direction of the intended motion.
* Types of friction: There are several types of friction, including:
* Static friction: This acts when two surfaces are at rest relative to each other and prevents them from moving.
* Kinetic friction: This acts when two surfaces are sliding relative to each other.
* Rolling friction: This acts when a round object rolls over a surface.
* Examples: Friction is everywhere in our daily lives:
* Pushing a heavy box across the floor.
* A car braking to a stop.
* A ball rolling to a stop on a table.
