What does the reading on a spring balance indicate when a brick begins...
Explanation:
The reading on a spring balance indicates the force of friction when a brick begins to move. This is because when an object is at rest, the force of static friction between the object and the surface it is resting on is equal and opposite to the applied force. However, once the applied force exceeds the maximum static frictional force, the object starts moving. At this point, the spring balance reading indicates the force of kinetic friction acting on the object.
Key Points:
- When the brick begins to move, the force of static friction is overcome by the applied force.
- The force of kinetic friction comes into play once the object starts moving.
- The reading on the spring balance at this point reflects the force of kinetic friction acting on the brick.
