"WebIf you push on a stationary block and it doesn't move, it is being held by static friction which is equal and opposite to your push. Once your push exceeds the maximum possible static friction (budging force = μN), then the block will start moving. The moving block will then experience kinetic friction which is smaller than the static friction. " - Friction 2 block problems

WebJan 5, 2024 · If the force on the first block does not exceed the maximum friction between the blocks and if the ground were frictionless, both blocks would move at the same speed. However if the force exceeded the maximum friction between the blocks the lower block will slide along the ground, and the upper block will also slide along the lower block.
