Question & Answer
Choose the Best Answer
The gravitational force acting parallel to the incline becomes weaker as it descends
The frictional force acting against the direction of motion increases
The normal force increases as the object moves down the slope
The object's mass increases as it accelerates down the incline
Understanding the Answer
Let's break down why this is correct
The frictional force pushes back against the object's motion, so the block slows down. Other options are incorrect because A common idea is that gravity weakens as the block goes down; Some think the normal force grows as the block moves.

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.
