Newton's three laws of motion

The normal force and the weight are ecual, so there aren't motion, the balls are in rest. The white ball acts on the orange balls with a unbalanced force, so this produces motion in the orange balls. The man apply a force over the box to produce a motion with acceleration. Then the man apply the same force in the heavier box, so there is less acceleration. The rocket goes up, because of the acting friction force: always goes opposite the motion. The reaction of the gases push the rocket up.
