[EX Q]: proper question: What makes static friction go up or down in responce to contact characteristics between an object and the surface it is on? 
 disfluent question: Who or no make that what makes static friction go up or down in response to contact characteristics between an object and the surface it is on? 
 context: Pushing against an object on a frictional surface can result in a situation where the object does not move because the applied force is opposed by static friction, generated between the object and the table surface. For a situation with no movement, the static friction force exactly balances the applied force resulting in no acceleration. The static friction increases or decreases in response to the applied force up to an upper limit determined by the characteristics of the contact between the surface and the object.
[EX A]:
applied force
