Which of these is NOT a Newtonian Law of Motion

• An object in motion remains in motion unless acted upon by an unbalanced force

• An object at rest remains at rest unless acted upon by an unbalanced force

• Force equals mass times acceleration

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

• Gravity acts upon all objects equally, mass will not change velocity
