What is Newton's 1st law?

• Law of Force and Acceleration

• Law of Inertia

• Law of Action-Reaction

• Law of motion

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

Newtons 3rd Law of Motion states:

• An object at rest will remain at rest unless acted upon by an outside force.

• For every action, there is an equal and opposite reaction

• The greater the mass of an object, the more force it will take to accelerate the object
