Physics Uncovered on Instagram: "static friction is the force that keeps two surfaces from moving when they’re touching but not sliding. it resists motion and stops an object from moving when a small push is applied. as the push increases, the friction force also increases until it reaches its maximum limit, known as limiting friction. once that limit is passed, the object begins to move and static friction is replaced by kinetic friction. example: a box won’t slide across the floor until you pu
