Q
Q: A 4 kg object is at rest on a table. What is the force of static friction acting on it?
Solution: If the object is at rest and no external force is applied, the static friction force is 0 N.
Steps: 5
Step 1: Identify the object. We have a 4 kg object on a table.
Step 2: Determine the state of the object. The object is at rest, meaning it is not moving.
Step 3: Consider external forces. Since no external force is applied to the object, it remains at rest.
Step 4: Understand static friction. Static friction acts to prevent motion. If there is no force trying to move the object, static friction is not needed.
Step 5: Conclude the force of static friction. Since the object is at rest and no external force is acting on it, the force of static friction is 0 N.
