Q: What is the effect of increasing the normal force on the frictional force between two surfaces?

Solution: Frictional force is directly proportional to the normal force. Increasing the normal force increases the frictional force.

Steps: 6

Step 1: Understand what normal force is. The normal force is the force that pushes two surfaces together. It acts perpendicular to the surfaces.
Step 2: Know what frictional force is. The frictional force is the force that resists the sliding motion between two surfaces in contact.
Step 3: Learn the relationship between normal force and frictional force. The frictional force depends on how hard the surfaces are pressed together, which is determined by the normal force.
Step 4: Realize that if you increase the normal force (for example, by adding more weight), the surfaces are pressed together more tightly.
Step 5: Understand that when the normal force increases, the frictional force also increases. This means it becomes harder to slide one surface over the other.
Step 6: Conclude that increasing the normal force leads to an increase in the frictional force.
