Maria pulled an empty cart to the library. When she leaves the library, the cart is full of books. How does the force of friction on the cart change?

• The force of friction increases because there is more mass.

• The force of friction decreases because there is more air pressure.

• The force of friction increases because the force of gravity decreases.

• The force of friction stays the same because Maria is still pulling the cart with the same force.
