Question & Answer
Choose the Best Answer
The frictional force decreases as the angle increases.
The frictional force remains constant regardless of the angle.
The frictional force increases with the angle until a maximum is reached.
The frictional force becomes zero at all angles of incline.
Understanding the Answer
Let's break down why this is correct
When the slope is steeper, the weight pulls the object more toward the ground, which lowers the normal force that pushes against the surface. Other options are incorrect because Some people think friction never changes with slope, but friction only exists if there is a normal push from the surface; It sounds like friction might grow until a limit, but friction is directly tied to the normal push, which decreases as the slope increases.

Definition
Friction Forces Analysis involves examining the direction and magnitude of forces, such as gravitational and frictional forces, acting on objects in different scenarios. By understanding how these forces interact, we can determine if an object will accelerate, remain stationary, or move in a particular direction based on friction coefficients and external influences.
