What is the main characteristic of the force of friction?
What is the main characteristic of the force of friction?
It is a self-adjusting force.
What is necessary for friction to occur between two surfaces?
What is necessary for friction to occur between two surfaces?
Relative motion or tendency of motion between the two surfaces.
How does the roughness of the surface affect friction?
How does the roughness of the surface affect friction?
More roughness leads to more friction, and smooth surfaces lead to less friction or even zero friction.
