* Static friction force increases proportionally to the normal force.
Here's why:
* Normal force: The normal force is the force exerted by a surface perpendicular to an object resting on it. It's essentially the force that counteracts the object's weight (which is directly proportional to its mass).
* Static friction: Static friction is the force that prevents an object from moving when a force is applied to it. The maximum static friction force is directly proportional to the normal force.
In Summary:
* Increased mass leads to increased weight which in turn leads to increased normal force.
* Increased normal force leads to increased maximum static friction force.
Example:
Imagine a box sitting on a table. If you increase the mass of the box, it will exert a greater force (weight) on the table. This increases the normal force the table exerts back on the box. As a result, it takes more force to get the box moving, indicating a higher maximum static friction force.
