It takes more force to accelerate the iron man on the left than the iron man on the right because the iron man on the left has more mass. This best describes

• Newton's first law, the law of inertia

• Newton's second law, the law of acceleration

• Newton's third law, the law of action reaction 

• The law of universal gravitation
