friction
Sliding large books requires more force than sliding small books because larger books have more mass and surface area, leading to increased friction with the surface they are sliding on. This increased friction makes it harder to overcome the resistance and slide the large books.
The force that makes it hard to pull the box is friction. Friction is a force that opposes the motion of objects sliding against each other.
This question is ambiguous. It depends on what force you are comparing the friction force with. Friction, itself, is a force, which will be directed in a direction OPPOSITE the sliding or attempted sliding of two surfaces.
The force that causes honey to drop on the floor is gravity. Gravity is the natural force that pulls objects towards the center of the Earth.
Sliding is made difficult by friction because rough surfaces "grab" whatever is attempting to slide. Sledding is easy because snow eases friction.
gravity
Gravity? the strength of the floor?
When you slide your hands together, the rough surfaces of your skin create friction that resists the motion. This frictional force makes it harder to slide your hands smoothly, causing the feeling of resistance as you try to move them.
It's the mystical force known as "little slow-speed electric motor below the floor of the cooking chamber".
The force of gavity on car exerts friction on the wheels and axle that eventually stop the car from exerting forward force.
Friction between the book and the floor creates resistance to its motion, making it difficult to push. The weight of the book also plays a role in increasing the force required to move it. Additionally, irregularities or imperfections on the floor's surface can further impede the book's movement.
Gravity. It's the same force which pulls things down even without water.
