Question & Answer
Choose the Best Answer
It is zero because the object started sliding.
It is equal to the weight of the object.
It is determined by the ratio of the static friction force to the normal force.
It increases as the object's speed increases.
Understanding the Answer
Let's break down why this is correct
Static friction coefficient is the maximum static friction force divided by the normal force. Other options are incorrect because The idea that friction becomes zero once sliding starts is a common mistake; Thinking the coefficient equals the object's weight is another misconception.
