Which of the following is not one of newton's three laws of motion?

• Law of inertia: an object will continue its motion unless acted on by an external force

• Law of force: the magnitude of a force is determined by the product of mass and acceleration

• Law of reactions: When a force is exerted by an object a reactionary for of equal size but opposite in direction occurs

• Law of universal gravitation: every particle attracts every other particle in the universe with a force
