Question & Answer
Choose the Best Answer
The gravitational force is decreasing
The normal force is increasing
Frictional force is acting against the motion
The object's mass is increasing
Understanding the Answer
Let's break down why this is correct
Friction is the force that pushes against the motion of an object on a surface. Other options are incorrect because It is easy to think that gravity must lessen to slow the object, but the pull of gravity stays the same while the object is on the incline; The normal force is the push from the surface that balances part of the object's weight.

Definition
Friction in Physics refers to the force that opposes motion between two surfaces in contact. It plays a crucial role in determining how objects move on surfaces and is influenced by the normal force and the friction coefficient. Understanding friction is essential for analyzing the behavior of objects on horizontal and inclined surfaces.
