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. Web10 apr. 2024 · Among them, α and β are two constants.
