Study Notes
Friction
- Static friction is less than sliding friction.
Types of Friction
- Rolling friction is less than static friction and sliding friction.
Watt Governor
- The height of a Watt governor is directly proportional to the speed.
- As the speed increases, the height of the Watt governor increases.
