Study Notes
Friction Overview
- Friction opposes motion, causing objects to slow and stop.
- It's a force resisting the relative sliding of surfaces in contact.
- Friction acts on all surfaces.
Air Friction
- Air friction affects falling objects, counteracting gravity.
Types of Friction
Rolling Friction
- Occurs when an object rolls.
- Example: Vehicle tires on a road.
Sliding Friction
- Also known as dry friction.
- Results from the bonding of surfaces rubbing against each other.
- Example: Moving a block of wood on sandpaper, pushing a book.
Fluid Friction
- Friction between moving objects and a fluid (liquid or gas).
- Example: Swimming, boat travel, airplane flight.
Static Friction
- Friction in stationary objects.
- Prevents objects from moving against a surface.
- Example: A notebook on a table.
