Answer
When an object moves at a constant velocity, the kinetic frictional force equals the applied force. Static friction equals the applied force when the object is at rest, and it can be greater than the applied force when the object is just about to move.

In the world of physics, kinetic friction kicks into action when two surfaces are sliding against each other. When the applied force equals kinetic frictional force, it simply means that the object is moving at a constant velocity – no acceleration here! Imagine sliding a book across a table; if you’re pushing just hard enough to keep it gliding smoothly, that’s equilibrium.
Now, static friction, on the other hand, is like a wise old guardian that keeps objects at rest until enough force is applied to break that grip. If static friction is greater than the applied force, the object remains still, like a stubborn cat refusing to budge. Once the applied force matches static friction, bam! The object starts to move, and kinetic friction takes over!
