Question & Answer
Choose the Best Answer
The normal force remains unchanged, but the frictional force decreases.
Both the normal force and the frictional force increase.
The normal force increases while the frictional force remains constant.
The normal force decreases while the frictional force increases.
Understanding the Answer
Let's break down why this is correct
The normal force is set by the object's weight and gravity; it does not change when the surface gets hotter. Other options are incorrect because Some think heat makes surfaces stronger and pushes the object up; A common mistake is to believe that a hotter surface lifts the object, raising the normal force.
