What are examples of sliding friction and static friction?

Answer 1

Static: A cars wheels (while car and wheels are stopped, or while car is moving and wheels are rolling), a doorstop, a rock on a hill (not sliding down) and the force keeping a nail in some wood.

Sliding: A cars wheels (during burnouts or when brakes are applied too hard and the car skids), dragging a computer mouse along a table, Ice skaters blades and a drink slid down the bar to you.

Answer 2

Sliding friction occurs when two surfaces slide past each other, like when you push a book across a table. Static friction acts between stationary objects and prevents them from moving when a force is applied, such as trying to push a heavy box on the floor.
