Final answer:

Friction's impact on actions such as turning a door knob and a soccer player running with studs is discussed, highlighting its dual role of usefulness and inconvenience.


Explanation:

Friction plays a crucial role in various actions:

  1. In turning a door knob, friction provides the necessary grip for the hand to rotate the knob smoothly.
  2. For a soccer player running with studs underneath, friction between the studs and the ground aids in traction and stability, allowing the player to sprint and change directions effectively.

It is clear that friction can be both useful and inconvenient depending on the context and desired outcome.
