Friction intuition animation

The video tutorial explains the concepts of static and kinetic friction using a block example. It describes how static friction prevents movement until a maximum force is reached, after which kinetic friction takes over with a constant force. The tutorial also introduces the coefficients of friction and demonstrates these concepts through a graphical representation, plotting friction force against applied force.

How is the maximum static friction force calculated?

Describe what happens to the friction force as the applied force continues to increase after the block starts moving.
