Danaya is moving heavy furniture by sliding it across the floor. She puts a blanket underneath the furniture. Why did this help her?
The blanket protects the side of the furniture from bumping against the wall.
The friction is smaller between the blanket and the floor than between the furniture and the floor.
The friction is larger between the blanket and the floor than between the furniture and the floor.
The blanket reduces the gravitational force between the furniture and the floor.
