PHY 101 Friction Objective Question

Question

What happens when the applied horizontal force F on a stationary object exceeds the maximum static frictional force f_s,max?
Options
A The object remains stationary.
B The object begins to slide along the surface.
Correct Answer
C The static friction force increases further.
D The normal force immediately becomes zero.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The lecture states that if F exceeds f_s,max, then the body begins to slide along the surface.

Hint

Once the maximum static friction is overcome, the object can no longer remain at rest relative to the surface.
