Sam is pushing a box with ten books in it. He adds ten more books to the box. If she continues pushing with the same force, what effect will the additional books have on the motion of the box?

• box will move more slowly due to the increase in masss

• box will move more slowly due to the increase in gravity

• box will move more quickly due to the decrease in mass

• box will move more quickly due to the decrease in friction
