Final answer:
To determine which force is static friction, we need to know the state of the object - whether it is at rest or in motion. Static friction would apply to the object at rest, and kinetic friction to the object in motion. Without this context, we cannot definitively identify static friction between Force 1 and Force 2.
Step-by-step explanation:
The student's question is related to the two types of frictional force: static friction and kinetic friction. Static friction acts on an object at rest, preventing it from starting to move. It has to be overcome by an applied force for the object to start moving. Once the object is in motion, it experiences kinetic friction. If the student has provided information on which of the two forces (Force 1 or Force 2) represents an object at rest and which represents an object in motion, the one representing the object at rest would be static friction. According to the information provided in the question itself, without additional context about the state of motion of the object, it is not possible to definitively conclude which force is static friction.
