Friction and Forces

How this simulation works

Use the Static Friction slider (μs) to set the threshold force needed to start the block moving, and the Kinetic Friction slider (μk) to set the drag that slows it once in motion. Press Start to apply a push to the block, Pause to freeze it mid-slide, and Reset to return it to the starting position. If the applied force is below the static threshold the block stays put; once it exceeds that threshold, the block slides and decelerates at a rate set by the kinetic coefficient until it comes to rest.
