Your interviewer will likely ask you knowledge-based questions to understand how well you are able to explain concepts to others. Be prepared for questions like this one by practicing a few possibilities ahead of time. In this case, static friction describes friction between two solid objects that are not moving relative to each other. If you park your car on a hill, static friction can prevent it from rolling down the hill, even though there aren't any moving components. This is different from kinetic friction, which typically describes the friction between two objects that are moving relative to each other. Static friction is typically higher than kinetic friction, but this is not always the case.
