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

According to Newton's second law of motion, if a rigid body of unchanging mass is observed accelerating, what must be happening?

• A force was once applied but is now not being applied.

• The mass must be changing.

• Unbalanced forces act "all crazy!!!" on an object.

• A force is being applied to the mass.
