A cardboard box on the floor is given a hard push. The force of the push is greater than the frictional force of the floor. What will happen immediately after the box is pushed?

• The box will speed up because the pushing force on the box continues to increase.

• The box will speed up because of the difference in magnitude of the two forces.

• The box will move at a constant speed because the force of the push is constant.

• The box will not move because the forces are balanced.

A fat dog and a thin dog both jump off of a diving board at the same time. Which dog has the most gravitational potential energy?

• The thin dog because it has less mass.

• The fat dog because it has more mass.

• They have the same amount because gravitational potential energy does not depend on mass.

• Neither dog has any gravitational potential energy.
