Static Friction
Kinetic Friction
Rolling Friction
Fluid Friction
Understanding the Answer
Let's break down why this is correct
When the block starts to move, the contact force changes to a force that opposes motion. Other options are incorrect because The idea that the block is still at rest is a misconception; Rolling friction is only for wheels or balls that roll.
