Questions & Step-by-Step Solutions
A 4 kg object is at rest on a table. What is the force of static friction acting on it?
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.
Static Friction – Static friction is the force that keeps an object at rest and prevents it from moving until a certain threshold is exceeded.
Equilibrium – An object at rest is in a state of equilibrium, meaning the net force acting on it is zero.
