Webthe coefficient of static friction is larger than the kinetic coefficient. The surface provides a higher friction force before it moves than when it is in motion. When the force reaches … WebStatic friction is the force of friction on an object that is not moving. If 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.
