Why is it harder to push a van filled with bowling balls than it is to push a van with basketballs?

• The mass of the car is greater than the mass of the basketballs

• The mass of the bowling balls is greater than the mass of the basketballs

• The van with the basketballs is bigger than the van with the bowling balls

• It should be equally as hard to push the two vans
