Assertion: graphite | /r/HasAspect | low coefficient of friction
Facets:
value: due to low shear force
type: CAUSE
Source sentences:
text: Graphite has a low coefficient of friction because there is less resistance when the two objects slide over each other with a layer of graphite between them.
text: Due to low shear force, graphite has a low coefficient of friction, and hence, it acts as a good lubricant.
