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

A squirrel sits on the ground and eats a donut. We know the forces on him must be balanced because...

• Forces are always balanced

• the squirrel is not accelerating

• squirrels are projectiles

• he's eating a donut
